✦ Synopsis
Selective Dimerization by a Radical Chain Reaction in γ-Irradiated Crystals of 1,3-Bis(3-acetoxyprop-1-ynyl)-4-methoxy-6-methylbenzene. -γ-Irradiation of (I) under vacuum forms the single dimer (II). Such an exclusive formation of a dimeric product by the γ-irradiation is observed neither for benzene solutions of (I) nor for crystals of other disubstituted bis(3-acetoxyprop-1-ynyl)benzenes. The crystal structure of (I) is responsible for the selective dimerization by the chain reaction. A mechanism for the chain reaction is proposed on the basis of the crystal structure.
