Oxidative addition of chloro-and dichloroacetic acid to alkenes to give alpha-Chloro- and alpha,alpha-Dichloro-butyrolactones with manganese(III)acetate

摘要

Oxidative addition of chloroacetic acid and dichloroacetic acid to slkenes with Mn(OAc)_3 to give alpha-chloro- and alpha,alpha-dichlorobutyrolactones proceeds in moderate to good yeild in MeCN containign one equivalent of the sodium salt of the carboxylic acid.
