Article abstract of DOI:10.1246/cl.1988.1449

Allylic phenylcarbamates prepared from allylic alcohols and phenyl isocyanate in situ reacted with aldehydes to give conjugated dienes in good yields in the presence of tributylphosphine and a catalytic amount of Pd(PPh3)4.This method proved to be suitable for the preparation of polyene compounds such as carotenoids.
