Alkylation of tetrabutylammonium dihydrogenophosphate by terpenic allylic sulphonium salts give the corresponding primary terpenic allylic phosphates in fair to moderate yields, without complex procedures of purification. The catalysis of the reaction by cuprous ion leads to the isolation of tertiary allylic phosphates.
