Photolysis of benzoylmethylene(triphenyl)phosphorane
Abstract
Direct(>3000 Å) and sensitized photolyses of benzoylmethylene(triphenyl)phosphorane in cyclohexene yielded 1:1·2 and 6·5:1 ratios of acetophenone and 7-norcaryl phenyl ketone, respectively, demonstrating that benzoylcarbene is a primary photoproduct.
