  Reactions of bis(iminophosphoranyl)methane, CH2(PPh(2)=N-aryl)(2), (BIPM; 1a, b) or 1, 1-bis(iminophosphoranyl)ethane (1, 1-BIPE; Ic) with Pd- and Pt-dichlorides containing weakly coordinating ligands (L) such as nitriles or cyclo-octadiene, afforded several products depending on the reaction time, type of ligand (la-c) or nature of the metal. The first reaction observed is a metal-assisted tautomerization of BIPM to aryl-N=PPh(2)-CH=PPh(2)-NH-aryl. When BIPM reacts with PdCl2(L)(2), exclusive formation of the C, N-chelate PdCl2CH(PPh(2)=N-aryl)(PPh(2)-NH-aryl)} (2a, b) is observed, whereas with 1, 1-BIPE(1c) a product mixture consisting of a C, N-chelate (2c) and an N, N'-chelate (3) is found. Orthometallation of the four-membered palladacycle (2) took place upon heating, giving the five-membered palladacycle [PdCl2(2-C6H4-PPh(NHI-pTol)-C'H-PPh(2)(NH-pTol)}-C, C'] (4). The molecular structure of 4 has been determined by X-ray crystallography, Reactions of BIPM (1a, b) with PtCl2(RC=N)(2) (R = phenyl, p-tolyl) afforded entirely different products: the six-membered platinacycles [PtCl(RC=N)aryl-N=C(R)-N=PPh(2)-CH=PPb2-NH-aryl}-C, N]Cl (5) and [PtCl2aryl-N=C(R)-N=PPh(2)-CH=PPh(2)-NH-aryl}-C, N] (6), due to an unexpected 2 + 2 cycloaddition of a nitrile with a P=N group.

  The reactions of cis- and trans-[PtCl2(NCR)2] (R = p-MeC6H4, p-CF3C6H4, o-MeC6H4, Et, Pr(n), Pr(i) or Bu(t)) complexes with 2 equivalents of -OCH2CH2Cl, generated by deprotonation of HOCH2CH2Cl with LiBu(n), afford in high yield the bis(DELTA2-1,3-oxazoline) derivatives cis-and trans-[PtCl2N=C(R)OCH2CH2}2]. The complexes have been characterized by their elemental analyses, IR, H-1 NMR, C-13-H-1} NMR and FAB mass spectra. The structure of trans-[PtCl2N=C(But)OCH2CH2}2] was established also by X-ray crystallography: monoclinic, space group P2(1)/n, a = 11.233(2), b = 8.741(2), c = 9.394(2) angstrom, beta = 101.61(3)degrees and Z = 2; R = 0.038 (R' = 0.042) for 2514 measured reflections with I greater-than-or-equal-to 3sigma(I). The N-C(R) and (R)C-O bond distances of 1.284(5) and 1.335(5) angstrom suggest that there is extensive electron delocalization within the N-C(R)-O system. The co-ordination geometry around Pt(II) is planar and the oxazoline rings are only slightly twisted. The formation of DELTA2-1,3-oxazolines from platinum(II)-co-ordinated nitriles has also been examined using HOCH2CH2Cl in the presence of the weak base NEt3. These reactions proceed through the initial formation of the bis(imido ester) complexes [PtCl2NH= C(R)OCH2CH2Cl}2], present as their (Z,Z), (EE) and (E,Z) conformers, which slowly convert to the final cyclic DELTA2-1,3-oxazoline derivatives.

  The pentacoordinate [PtHP(OEt)3}4]BF4 (1) hydride complex was prepared by allowing the tetrakis(phosphite) PtP(OEt)3}4 to react with HBF4.Et2O at -80 degrees C. Depending on the nature of the acid used, however, the protonation of the related PtPPh(OEt)2}4 complex yielded the pentacoordinate [PtHPPh(OEt)2}4]BF4 (3) or the tetracoordinate [PtHPPh(OEt)2}3]Y (4) [Y = BF4- (a), CF3SO3- (b), Cl- (c)]
