Electronically excited stilbene (1*) is trapped by 8-substituted caffeine derivatives (2a-f) or 2-chloro- (14) and 2-aminobenzothiazole (21) with variable results.While the electron-rich systems (2c,d) produce mostly propellanes, the halogeno compounds 2a,b and 14 react predominantly via insertion into the C-halogen bond.With 14 there occurs also some C-S insertion, with 21 only N-H insertion.Numerous succeeding reactions are elucidated and the reaction mechanisms discussed.Stilbene (1) photoadds hydrogen chloride to yield 16.
