The reduction of α-bromocamphor by tertiary amines
The reduction of α-bromocamphor to camphor by N,N-dimethylaniline (DMA) at high temperatures (>200 deg C) proceeds via a free radical chain sequence.The reduction can be effected with DMA or triethylamine (TEA) in acetonitrile at much lower temperatures in the presence of di-tert-butylperoxide.The chain termination step is the dimerization of the camphor radical.These reductions presumably constitute an example of an electron transfer chain mechanism involving a tertiary amine as the chain propagating species. Key words: reduction, tertiary amines, α-bromocamphor, chain reaction.
