- 論文の詳細を見る
A new method for isomerization of (Z)-stilbenes into the (E)-isomers, catalyzed by diaryl disulfide, has been developed. Diphenyl disulfide is the most versatile catalyst, smoothly effecting the isomerization of stilbene, methoxystilbenes, and hydroxystilbenes. For dimethoxystilbenes, whose isomerization by diphenyl disulfide is slow, 4,4'-dinitrodiphenyl disulfide or 2,2'-dipyridyl disulfide greatyl accelearted the isomerization. Diphenyl disulfide is ineffective for the isomerization of stilbenes bearing electron-attracting substituents(s). The isomerization of these stilbenes was greatly accelerated by catalysts bearing an electron-donating substituent, such as 4,4'-dimethoxydiphenyl disulfide.
