ABSTRACT:
There is disclosed a novel process for converting allylic amines, having a hydrogen bonded to a carbon .delta. to the amino group, to a diene in the presence of a zero valent palladium phosphine complex and a weak acid. The process has been used to make novel compositions containing 7-methoxy-3,7-dimethyloctadienes which are useful as odorants and flavorants.
