Title: Photochemical Reactions of α-Bromoacetylarenes Studied by Product Analysis and Laser Flash Photolysis
Abstract: Abstract The hydrogen abstraction reaction and rearrangement reaction of aroylmethyl radicals were studied by product analyses and transient absorption spectroscopies. The α-bromoacetylarenes examined in this study gave aroylmethyl radicals by C–Br bond cleavage upon photoirradiation. According to the results of the product analysis, the rearrangement reaction takes place in the aroylmethyl radicals produced on irradiation of 1-bromoacetylnaphthalene (1-BAN) and 9-bromoacetylanthracene (9-BAA). The rate constants of the rearrangement reaction resulting in an arylmethyl radical and the hydrogen abstraction reaction resulting in an acetylarene for aroylmethyl radicals were estimated based on the results of laser flash photolysis and product analysis.
