DOI:10.1055/s-1989-27143
日期:——
α-Methylthio-α,β-unsaturated sulfones 3 prepared from aromatic aldehydes 1 and sulfone 2 react with sodium hydrogen telluride in ethanol to undergo reductive desulfonylation to give vinyl sulfides 4 with certain extent of stereospecificity. A new route to one carbon homologation of aromatic aldehydes 1 to 5 is achieved by hydrolysis of 4 with titanium tetrachloride.

Nucleophilic aromatic substitution reactions with imidazole of haloarenes having strongly electron-withdrawing groups were studied under ultrasonic and microwave irradiations. The course of the SNAr reactions was found to be strongly dependent on the electron-withdrawing properties of the substituents as well as on the leaving ability of the halogen atom. Microwave irradiation allowed to shorten the reaction time and to increase the yields compared with ultrasonic irradiation.
