α-arylation vs. α-arylhydrazonylation of alkyl aryl ketones with arylazo tert-butyl sulfides
Add time:08/07/2019 Source:sciencedirect.com

Potassium enolates of alkyl aryl ketones react selectively in DMSO with phenylazo 1a and 4-methylphenylazo tert-butyl sulfide 1b undergoing respectively effective α-phenylation via SRN1 and α-(4-methylphenyl)hydrazonylation via elimination-addition.
