Tris(trimethylsilyl)silane, in contrast with tributyltin hydride, reduces acid chlorides to the corresponding decarboxylated hydrocarbons via a free radical mechanism. This methodology could be a viable alternative to Barton's decarboxylation reaction. Tributyltin hydride reacts spontaneously at amb
