Tris(tetra-n-butylammonium) hydrogen pyrophosphate was used to prepare dimethylallyl pyrophosphate (1-OPP), 7-methylocta-2,6-dien-1-yl pyrophosphate (2-OPP), geranyl pyrophosphate (3-OPP), 2-flourogeranyl pyrophosphate (4-OPP), and farnesyl pyrophosphate (5-OPP) from the corresponding alcohols in moderate yields by a two-step sequence via the corresponding primary, allylic bromides.
