Abstract
The photo-Claisen type rearrangement of 2-(1-methoxycarbonylnaphthyl)methyl phenyl ether derivatives 1a-f was investigated. The 2-( 1-methoxycarbonyln aphthyl)methyl radical and its fluorescence by use of two colored laser fla sh photolysis (LFP) technique were directly observed as a reactive intermed iate. The reactivity of the photorearrangement depended on the p-substituen ts on the phenoxy group.
