AbstractThe photoinduced isomerization reaction in benzene solution from RNC to RCN was found to follow a free radical chain mechanism, where R represented -C(CH3)(3), -CH(CH3)(2), -CH3, -CH2CH3, and -CH2CH2CH3, respectively. The alkyl radical intermediates R. in the isomerization reaction were detected by electron spin resonance (ESR) spectroscopy in combination with spin traps PEN and ND. Initiation of the isomerization in condensed-phase can be explained by a homolytic bond breaking between R group and nitrogen atom in the photo-irradiated isonitrile derivatives at room temperature. The products analysis by CC was also supported the conclusion of free radical chain mechanism. (C) 1999 Elsevier Science S.A. All rights reserved.
