Electrophilic attack of 1 equiv of I2 on a PCsp2 carbon of the Pt(II) complex cis-[Pt{Ph2PCH-C(-O)Ph}2] (1) afforded cis-[Pt(I)[Ph2PCH-C(-O)Ph}{Ph2PCH(I)C(O)Ph}] (2) in 90% yield. Complex 2 was subsequently deprotonated by NaOEt in ethanol to give the bis(enolato) complex cis-[Pt{Ph2PCH-C(-O)Ph}{Ph2PC (I)-C(-O)Ph}] (3). This alpha-phosphino, alpha-iodo enolato complex was obtained directly and quantitatively by the reaction of 1 with 1 equiv of N-iodosuccinimide (NIS). When 2 equiv of NIS was used, the symmetrical complex cis-[Pt{Ph2PC(I)-C(-O)Ph}2] (4) was formed selectively. In contrast to I2, NIS was also able to functionalize the phosphino enolate ligand of complexes [(C N)Pd{Ph2PCH-C(-O)Ph}] to give the correspending iodo derivatives [(C N)Pd{Ph2PC(I)-C(-O))Ph}] (C N = dmba (5) or 8-mq (6)). These represent the first examples in which a phosphino enolate C-H bond has been directly functionalized, i.e. replaced by a C-X bond. Attempts to use this procedure with cis-[Ni{Ph2PCH-C(-O)Ph}2] or with [Ni(Ph) {Ph2PCH-C(-O)Ph}(PPh3)] were unsuccessful. Reaction of 5 with Pd(dba)2 in the presence of tetramethylenediamine (tmeda) or 2,2?-bipyridine (bipy) afforded [(dmba)Pd{Ph2PC-C(-O)Ph}Pd(I)(tmeda)] (7) and [(dmba)Pd{Ph2PC-C(-O)Ph}Pd(I)(bipy)] (8), respectively. The solid state structures of complexes 5 and 7·CH2Cl2 have been determined by single-crystal X-ray diffraction: 5 crystallizes in the monoclinic space group P21/n with Z = 4 in a unit cell of dimensions a = 12.867(3) A, b = 10.625(3) A, c = 19.509(6) A, and beta= 102.23(2); 7·CH2Cl2 crystallizes in the monoclinic space group C2/c with Z = 8 in a unit cell of dimensions a = 35.906(3) A, b = 13.565(3) A, c = 15.775(2) A, and beta= 95.099(10). Complex 7 contains two palladium(II) centers, in a square-planar environment, connected by the P-C unit of a phosphino enolate ligand which adopts an unprecedented mu-mu2(P,C):eta2(P,O) bonding mode. The two coordination planes are almost orthogonal and make a dihedral angle of 88.0(2), which minimizes the steric hindrance between the ligands.
