T. Karatsu et al., FEATURES OF THE QUANTUM CHAIN PROCESS IN THE PHOTOCHEMICAL ONE-WAY ISOMERIZATION OF 2-ANTHRYLETHYLENES, Bulletin of the Chemical Society of Japan, 67(11), 1994, pp. 3030-3039
Regarding 2-anthrylethylenes which undergo a photochemical cis-to-tran
s one-way isomerization, their preparative methods are presented. The
isomerization of ArCH=CHPh and ArCH=CH(2-naphthyl) (Ar: 2-anthryl) pro
ceeds through a quantum chain process slightly more efficiently than A
rCH=CH(t)Bu. The origin of the high efficiency in the quantum chain pr
ocess of these ethylenes is discussed.
