Photocyclodimerization of alkyl, benzyl, and trimethylsilyl vinyl ethers in the presence of 1,4-dicyanonaphthalene
Abstract
Irradiation of alkyl, benzyl, and trimethylsilyl vinyl ethers in the presence of 1,4-dicyanonaphthalene in benzene affords trans- and cis-head-to-head cyclodimers in a 1:1 ratio.
