Benzene and 23 monosubstituted and 32 disubstituted derivatives of benzene were optimized for minimum energy structures using the B3LYP/cc-pVTZ method. The force fields of all the compounds were evaluated at their optimized geometries using the same method and basis set. In order to understand the effect of substitution(s) on the aromaticity of benzene, the aromaticity index based on interaction coordinates (AIBIC) values were computed for each and the change from the benzene value was obtained. This difference, the substituent effect based on interaction coordinates (SEBIC), quantifies the effect of the substituent on the aromaticity of benzene ring satisfactorily. It is found that the AIBIC of disubstituted benzenes (XC6H4Y) could be predicted well by adding the respective SEBIC(C6H5X) and SEBIC(C6H5Y) values to the AIBIC of benzene. The projected force fields of the meta and para fragments of the monosubstituted benzenes when chosen properly contain the information about the directing influence of the substituent in terms of the electron density based on interaction coordinates (EDBIC). When the EDBIC(para) > EDBIC(meta) relative to benzene, the substituent is ortho-para directing, while when the reverse is true, it is meta directing. The effect of conformational changes on aromaticity has been studied using aminophenols and dihydroxybenzenes. The additivity rule and the EDBIC concept work adequately well in that the methods can have several useful practical applications that will benefit various areas of science. A good understanding of the substituent effects and the ability to predict them should add a new dimension to the applications of AIBIC.

Nowadays, diabetes and its associated inflammatory complications are important public health problems worldwide. Market limitations of drugs with dual actions as anti-inflammatory (AI) and anti-diabetic have been led to a temptation for focusing on the discovery and development of new compounds with potential AI and antidiabetic activities. Herein, we synthesized two new series containing pyrazole ring with vicinal diaryl rings as selective COX-2 moiety and thiazolidindione (series 12a-f) or thiazolidinone (series 13a-f) as anti-diabetic moiety and the two moieties were linked together with methylene or methylenehydrazone functionality. The two series were evaluated for their COX inhibition, AI activity and ulcerogenic liability and for the anti-diabetic activity; 12a-f and 13a-f were assessed in vitro against alpha-glucosidase, beta-glucosidase, in vivo hypoglycemic activity (one day and 15 days studies) in addition to PPAR. activation study. Four compounds (12c, 12f, 13b and 13f) had higher COX-2 S.I. (8.69-9.26) than the COX-2 selective drug celecoxib (COX-2 S.I. = 8.60) and showed the highest AI activities and the lowest ulcerogenicity than other derivatives. Also, two thiazolidindione derivatives 12e and 12f and two thiazolidinone derivatives 13b and 13c showed higher inhibitory activities against alpha- and beta-glucosidase (% inhibitory activity = 62.15, 55.30, 65.37, 59.08 for alpha-glucosidase and 57.42, 60.07, 58.19, 66.90 for beta-glucosidase respectively) than reference compounds (acarbose with % inhibitory activity = 49.50 for alpha-glucosidase and D-saccharic acid 1,4-lactone monohydrate with % inhibitory activity = 53.42 for beta-glucosidase) and also showed good PPAR-gamma activation and good hypoglycemic effect in comparison to pioglitazone and rosiglitazone. Moreover, Shape comparison and docking studies were carried out to understand their interaction and similarity with standard drugs.

Acetic acid mediated regioselective synthesis of novel 2,4,5- trisubstituted thiazole derivatives has been reported by a domino reaction of thiosemicarbazide and aldehydes/ ketones/ isatin, to generate thiosemicarbazones ( in situ) followed by addition of arylglyoxal and active methylene/ activated C- H acids/ pyrazole/ indole in ethanol at 80 1C. The products are obtained in high yields by a simple work up. Metal free, short reaction time and high yields are some merits of this methodology.

An efficient and sustainable synthetic protocol has been presented to synthesis and 5-substituted 1H-tetrazole privileged heterocyclic substructures. The synthetic protocol involves two-component reaction between aryl nitriles and NaN3 in water using complex of L-lysine-palladium nanoparticles (NPs) modified Fe3O4 nanoparticles as magnetically separable, recyclable, and reusable heterogeneous catalyst. Magnetically retrievable L-lysine-Pd(0) modified Fe3O4 nanoparticles were applied in [2 + 3] cycloaddition synthesis of 5-substituted 1H-tetrazoles. The advantages of this strategy include easy recovery and efficient reusability of the expensive Pd NPs, obtaining high yields of [2 + 3] cycloaddition, short reaction times, and all of the reported synthetic strategies are being performed in water as green solvent for a wide range of substrates.

A new synthesis of 2-aroylbenzothiazoles via iodine-promoted domino transformations of anilines, acetophenones, and elemental sulfur was demonstrated. The highlights of this tandem synthesis are (1) easily available anilines and acetophenones as feedstock; (2) transition metal-free conditions; (3) inexpensive, nontoxic, easy handling, and abundant elemental sulfur as a building block. This synthetic strategy would complement the existing methods in the synthesis of this important heterocyclic scaffold. To our best knowledge, the formation of 2-aroylbenzothiazoles from simple anilines, acetophenones, and elemental sulfur was not previously reported in the literature.

The synthesis, electronic structure, and reactivity of a uranium metallacyclopropene were comprehensively studied. Addition of diphenylacetylene (PhC equivalent to CPh) to the uranium phosphinidene metallocene [eta(5)-1,2,4-(Me3C)(3)C5H2](2)U=P-2,4,6-tBu(3)C(6)H(2) (1) yields the stable uranium metallacyclopropene, [eta(5)-1,2,4-(Me3C)(3)C5H2](2)U[eta(2)-C2Ph2] (2). Based on density functional theory (DFT) results the 5f orbital contributions to the bonding within the metallacyclopropene U-(eta(2)-C=C) moiety increases significantly compared to the related Th-IV compound [eta(5)-1,2,4-(Me3C)(3)C5H2](2)Th[eta(2)-C2Ph2], which also results in more covalent bonds between the [eta(5)-1,2,4-(Me3C)(3)C5H2](2)U2+ and [eta(2)-C2Ph2](2-) fragments. Although the thorium and uranium complexes are structurally closely related, different reaction patterns are therefore observed. For example, 2 reacts as a masked synthon for the low-valent uranium(II) metallocene [eta(5)-1,2,4-(Me3C)(3)C5H2](2)U-II when reacted with Ph2E2 (E=S, Se), alkynes and a variety of hetero-unsaturated molecules such as imines, ketazine, bipy, nitriles, organic azides, and azo derivatives. In contrast, five-membered metallaheterocycles are accessible when 2 is treated with isothiocyanate, aldehydes, and ketones.
