An electrochemical epoxidation of unactivated olefins using water as the source of oxygen atoms has been developed. The epoxidation reaction employs seminormal-BrCH2CH2OH as the mediator, which shows good functional group compatibility, and can easily be performed on the gram scale. A wide range of unactivated olefins could be tolerated to give the functionalized epoxides with satisfactory results
The present invention provides a photoresist composition containing: a resin which contains a structural unit derived from a compound having an acid-labile group and which is insoluble or poorly soluble in an alkali aqueous solution but becomes soluble in an alkali aqueous solution by the action of an acid; an acid generator and a compound represented by the formula (I):
