Abstract

2-(Dideuteriomethylene)-1, 1-bis (4-methoxyphenyl) cyclopropane (d 2-1) undergoes degenerate rearrangement in both singlet-and triplet-sensitized electron-transfer photoreactions. Nanosecond time-resolved absorption spectroscopy on laser flash photolysis of the unlabeled 1 with 9, 10-dicyanoanthracene, 1, 2, 4, 5-tetracyanobenzene, or N-methylquinolinium tetrafluoroborate as an electron-accepting photosensitizer gives rise ...
