A novel palladium-catalyzed decarbonylation of aroyl phosphine oxides to prepare phosphine oxides from carboxylic acids is developed. Without the adjacent “anchoring atom”, the challenging C–P bond activation is achieved in high selectivity. The disclosure of this reaction provides a new example of C–P bond activation and helps to extend the understanding of the property of C–P bond.

New aroyl diphenyl phosphines (1f-i) substituted with ?-functions in ortho-positions of the aroyl part have been synthesized and photolyzed in benzene.In two cases (1h and i) 1.2- and 1.4-addition products of photochemically formed diphenylphosphinous acid (3) with acetone or phenanthrene quinone (8) are isolated in 59percent yields.Moreover, in neighboring-group participations aroyl radicals formed by competing α-cleavages of 1g-i yield 5- and 6-membered hetero- and carbocycles: xanthone (6), 3,3'-dimethoxy 3,3'-diphthalidyl (7), or the phenanthrene derivative 9, respectively.
