New syntheses of aryl isothiocyanates

Primary aromatic amines are readily converted into arylimino-1,2,3-dithiazoles 2 and the derived cyanothioformanilides 6, both of which are rapidly cleaved by ethylmagnesium bromide in hot THF to give the corresponding isothiocyanates. The transformation 2?6?ArNCS can be performed as a ‘one-pot’ operation. The imines 2 are also converted, more slowly, into the isothiocyanates by sodium hydride in hot THF, via the cyanothioformanilides 6. Conversion of the anilides 6 into isothiocyanates is much faster under microwave irradiation in 2,6-lutidine. Mechanisms are proposed for these reactions.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. Formula: C8H9NO2, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 22013-33-8, in my other articles.

Regioselective hydroboration-oxidation and -amination of fluoro-substituted styrenes

Hydroboration of fluorinated styrenes with common hydroborating agents results in polymerization. However, regioselective hydroboration has been achieved by utilizing iodoborane-dimethyl sulfide. A series of fluorinated beta-phenethyl alcohols and amines were synthesized via this methodology.

I2 promoted domino oxidative cyclization for one-pot synthesis of 2-acylbenzothiazoles via metal-free sp3 C-H functionalization

An I2 promoted domino protocol was developed to construct 2-acylbenzothiazoles from simple and readily available aromatic ketones/unsaturated methyl ketones and o-aminobenzenethiols. The reaction proceeded smoothly under metal-free and peroxide-free conditions.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.SDS of cas: 2879-20-1, you can also check out more blogs about2879-20-1

Photocatalytic decarboxylative alkenylation of alpha-amino and alpha-hydroxy acid-derived redox active esters by NaI/PPh3 catalysis

Herein, we report the photocatalytic decarboxylative alkenylation reactions of N-(acyloxy)phthalimide derived from alpha-amino and alpha-hydroxy acids with 1,1-diarylethene, and with cinnamic acid derivatives through double decarboxylation, using sodium iodide and triphenylphosphine as redox catalysts. The reaction proceeds under mild irradiation conditions with visible blue light (440 nm or 456 nm) in an acetone solvent without recourse to transition-metal or organic dye based photoredox catalysts. The reaction proceeds via photoactivation of a transiently self-assembled chromophore from N-(acyloxy)phthalimide and NaI/PPh3. Solvation plays a crucial role in the reactivity.

Direct alpha-iodination of aryl alkyl ketones by elemental iodine activated by 1-chloromethyl-4-fluoro-1,4-diazoniabicyclo[2.2.2]octane bis(tetrafluoroborate)

Selective introduction of an iodine atom at the alpha-carbonyl position in various aryl alkyl ketones was effectively achieved by reaction of target molecules with elemental iodine in the presence of N-F reagents. The best results were obtained by using 1-chloromethyl-4-fluoro-1,4-diazoniabicyclo[2.2.2]octane bis(tetra-fluoroborate) (Selectfluor F-TEDA-BF4) as the iodination mediator and methanol as the solvent. Despite a strongly activated aromatic ring, iodomethyl derivatives were thus exclusively obtained from the corresponding hydroxy and methoxy substituted acetophenone derivatives, 3-acetylindole and 2-acetylbenzofuran, while the alpha-iodo derivative was the main product in the case of iodination of 1,5,6,7-tetrahydro-4H-indol-4-one and 6,7-dihydro-1-benzothiophene-4(5H)-one.
