摘要

MX 2 (PPh 3) 2 (M= Ni, Pd, Pt; X= Cl, Br) and Co 2 (CO) 8 catalyze alkoxy-and aminocarbonylation of geminal dibromoalkanes, R 1 R 2 CBr 2 (R 1, R 2= H and CH 3). In the course of the catalysis, initial formation of the transition metal ketene complexes, M (CH 2= C= O) L 2, was followed by the reaction with alcohols to yield carbalkoxymethyl metal intermediate leading to esters.
