S. Yakabe et al., ALPHA-CHLORINATION OF KETONES WITH SODIUM-CHLORITE, MN(ACAC)(3) AND ALUMINA IN DICHLOROMETHANE, Synthetic communications, 28(1), 1998, pp. 131-138
Chlorination of a variety of aliphatic, alicyclic, and aromatic ketone
s with a reagent combination of NaClO2 and Mn(acac)(3) catalyst can be
readily performed in dichloromethane to afford alpha-chloroketones in
good yield under mild and neutral conditions with the aid of chromato
graphic neutral alumina.
