Oxidation of aliphatic 2,2-dichloroalkanals by HNO3 in CH 2Cl2: An easy and eco-friendly route to the corresponding 2,2-dichloroalkanoic acids

A simple, economically convenient, and eco-compatible procedure for the oxidation of 2,2-dichloroalkanals to the corresponding alkanoic acids has been set up, employing HNO3 in CH2O2, in the presence of NaNO2 as catalyst.

2,2-dichloroaldehydes and 2,2-dichlorocarboxylic acids from 2- picoline·HCl catalyzed chlorination of aldehydes

An efficient preparation of 2,2-dichloroaldehydes and 2,2- dichlorocarboxylic acids has been achieved by chlorination of aldehydes using 2-picoline hydrochloride as recoverable catalyst.

α,α-DICHLOROALDEHYDES AND α,α-DICHLOROCARBOXYLIC ACIDS FROM LONG CHAIN 1-ALKANOLS. IMPROVED CHLORINATION IN THE SYSTEM DMF-CHCl3-MgCl2

Production of α,α-dichloroaldehydes by direct chlorination of 1-alkanols with chlorine gas, catalyzed by DMF and DMF*HCl, was extended to long chain compounds (CnH2n+1OH; n = 5, 6, 8, 10, 12, 14, 16, 18).Two problems specific to the longer chains were solved to obtain isolated yields in the range 70-85 percent; a) parasitic radical chlorination was largely controlled by shielding from light; b) alkyl alkanoate side product (8 percent for n = 8 but 25 percent for n = 16 or 18) was decreased to 0-2 percent in the presence of MgCl2*H2O.Homogeneity of the reaction medium was improved with chloroform as a cosolvent.Oxidation of the aldehydes to dichlorocarboxylic acids proceeded smoothly with aqueous KMnO4 up to the tetradecanal.For the longer chains 30 percent hydrogen peroxide-NaHCO3 in acetone (overnight at 48-52 deg C) was the preferred oxidant.
