| Abstract: | The reactions of Pd (dba)2 (dibenzylidene acetone palladium (0)) and Pt (dba)2 (dibenzylidene acetone platinum (0)) with BPPY (Benzoyl Methylene Triphenylphosphorane) and BBuPY (Benzoyl MethyleneTri-n-butylphosphorane) in (1:2) ratios using tetrahydrofuran as solvent have yielded Pd (dba)(BPPY)2 (1), [Pd (dba)(C(H)COPh(PPh2-o-C6H4)][PPh3CH2COPh](2), Pd (dba)(BBuPY)2 (3), and Pt (dba)(BPPY)2 (4) complexes. Upon heating complex (1) in THF, a cyclization reaction occurred to give complex (2). The products (1), (2), (3), and (4) are studied by IR, 1H, 31P, and 13C NMR technique. |
