Abstract

The phosphorus ylides Ph3PCHC (O) C6H4R (R= 4-Me 1a, 4-Br 1b) react with PdCl2 in equimolar ratios to give the C, C-orthopalladated [Pd {CHP (C6H4) Ph2CO-C6H4–R)}(μ-Cl)] 2 (R= 4-Me 2a, 4-Br 2b) which react with NaClO4/dppe, NaClO4/dppm, py and PPh3 to give the mononuclear derivatives [Pd {CH {P (C6H4) Ph2} COC6H4-R}(dppe-P, P′)[(ClO4)(R= 4- Me 3a, 4-Br 3b),[Pd {CH {P (C6H4) Ph2} COC6H4-R}(dppm-P, P′)[(ClO4 ((R= 4-Me 4a, 4 ...
