Methyl α-chloro- or α,α-dichloro-esters are obtained in excellent yields by oxidation chlorination of 2-alkyl-4,5-dimethyl-1,3-dioxolanes with trichloroisocyanuric acid.

Methyl 2,2-dichloro or 2-bromo-2-chloro carboxylates were obtained in excellent yields by oxidation-chlorination of 2-(1-haloalkyl)-4-methyl-1,3-dioxolanes with trichloroisocyanuric acid.

A method is described for the synthesis of α,α-dichloroaldehydes, free from monochloroaldehyde, by chlorination of aldehydes or alcohols in dimethylformamide at 40-90 deg C.Results are reported for : (yield percent) propanal (90), butanal (78), pentanal (78), 3-methylbutanal (90), propanol (64), butanol (78), 3-methylbutanol (52), pentanol (66), 3,3-dimethylbutanol (86), hexanol (66), 2-phenylethanol (51), 3-phenylpropanol (54), 1,5-pentanediol , 1,6-hexanediol .Oxidative conversion (KMnO4, K2Cr2O7, H2O2-NaHCO3) into α,α-dichlorocarboxylic acids and methyl esters is discussed.
