Quality Control of 2,2-Diphenylacetonitrile. Recently I am researching about CHEMISTRY; COMPLEXES, Saw an article supported by the National Natural Science Foundation of ChinaNational Natural Science Foundation of China (NSFC) [21871029, 21573021, 21672024]; Deutsche Forschungsgemeinschaft (DFG) through the Heisenberg programGerman Research Foundation (DFG) [WA 2513/6]; Projekt DEAL. Published in WILEY-V C H VERLAG GMBH in WEINHEIM ,Authors: Wang, DQ; Ding, WJ; Hou, GH; Zi, GF; Walter, MD. The CAS is 86-29-3. Through research, I have a further understanding and discovery of 2,2-Diphenylacetonitrile
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.
Bye, fridends, I hope you can learn more about C14H11N, If you have any questions, you can browse other blog as well. See you lster.. Quality Control of 2,2-Diphenylacetonitrile
