Direct carbonylation of polychloroalkanes into acid chlorides using metallic salts ternary systems: an example of multistep catalysis
Abstract
A catalytic cycle for the direct carbonylation of CCl4 into CCl3COCl, catalysed by metallic salts mixtures, e.g. AlCl3/MCln/CuCl, under unexpectedly mild conditions, is proposed on the basis of FTIR, 17O and 27Al NMR spectroscopic studies.1
