Telomerization of vinyl chloride by polychloroalkanes containing the CCl3 group in the presence of iron pentacarbonyl and alcohol

Abstract

1. The radical telomerization of vinyl chloride by 1,1,1,3-tetrachloropropane and 1,1,1-trichloroethane was studied in the presence of Fe(CO)5 in isopropyl alcohol medium, leading to the formation of compounds with the structure RCH2CCl2 (CH2CHCl)nCl, where R=H, ClCH2. Telomer homologs with n=1–3 were isolated, and their structure demonstrated. 2. Iron pentacarbonyl, in conjunction with isopropyl alcohol, is not only an initiator of this telomerization, but at definite concentrations it participates in chain propagation, changing the yields of the telomer homologs and the particular transfer constants.
