The epoxidation of 1,4-bis(allyloxy)butane as a model for allyl ethers with 30 wt% hydrogen peroxide under two phase conditions with an onium salt as the phase transfer catalyst was studied. The reaction led to two epoxides, monoepoxide (1-allyloxy-4-glycidyloxybutane (1)) and diepoxide (1,4-bis(glycidyloxy)butane (2)). The influence of the type of the phase transfer catalyst -onium salt- was studied.
