The reaction of substituted cinnamic alcohols with bis(sym-collidine)bromine(I) hexafluorophosphate was examined. In general no oxetane was obtained when a substituent was fixed on the carbon carbon double bond. However, oxetanes were formed in high yields when two substituents were present in a of
