摘要

The photosensitized (electron transfer) irradiation of several conjugated 1, 1-diphenyl alkenes, in acetonitrile with 1, 4-dicyanobenzene or 1-cyanonapthalene as electron accepting sensitizer and 2, 6-lutidine as base, leads essentially quantitatively to tautomerization to the less stable unconjugated isomer (s). The proposed mechanism for this reaction involves formation of the alkene radical cation and sensitizer radical anion ...
