The carbonyls Fe(CO)5, Mn2(CO)10, Mo(CO)6, and W(CO)6 initiate the selective reduction of the CC13 group to the CHCl2 group by thiols. The reduction systems thiol + Mn, Mo, and W carbonyls have been used for the first time.The reduction of CCl3(CO2)nCl (n=4, 6, 8), CCl3(CH2)5CH3, CCl3CH2CH(CH3)CH2CHCl-CH3, and CCl3CHC1(CH2)3Cl showed that Fe(CO)5 and Mn2(CO)10 were the most effective initiators.
