  Chelated palladium and platinum complexes of diphosphinite ligands, ch₂(o-c₆h₄opph₂)₂ and ph₂po(ch₂)₃opph₂: characterization and catalytic activity

  摘要：

  The novel 10-membered chelated metal complexes have been synthesized by the reaction of known ligand 1, CH2(o-C6H4OPPh2)(2), and 2, PPh2O(CH2)(3)OPPh2, with starting complexes, MCl2COD[M = Pd (1a, 2a), Pt (1b, 2b)]. The characterization of new complexes has been performed by utilizing P-31{H-1}-NMR, C-13{H-1}-NMR, H-1-NMR, and FT-IR spectroscopic methods and elemental analysis. Also, the structures of complexes 1a and 1b have been determined by X-ray crystallography. Complexes 2a and 2b turned into dimer structures (2a and 2b) during the recrystallization process Complexes 1a and 2a are very effective catalysts in the Suzuki-Miyaura CC cross-coupling reactions of aryl bromide with phenylboronic acid.

  Bromotricarbonylrhenium(I) complexes [ReBr(CO)(3)L] [L = Ph2PO(CH)(3)OPPh2 (L), (Pr2PO)-Pr-i(CH2)(2)(OPPr2)-Pr-i (L-2), Cy2PO-(CH2)(2)OPCy2 (L)] were prepared by reaction of [ReBr(CO)51 with L. X-ray crystallography showed them all to be mononuclear, with the CO ligands fac. Subsequent reaction with AgOTf gave fac-[Re(OTf(CO)(3)L], as shown by IR and NMR spectra. By contrast, reaction of [ReH(CO)(5)] with L1-3 gave hydrido complexes, the nuclearity and stereochemistry of which depended on the identity of L, as was confirmed by X-ray crystallography of mer-[ReH(CO)(3)L-1], fac-[ReH(CO)(3)L-2] and [(ReH(CO)4}2(p-L 3)]. Protonation of the hydrido compounds at 183 K with HBF4 center dot OMe2 gave the corresponding non-classical cationic dihydrogen complexes (T-1(min) similar to 15 ms at 400 MHz), which released H-2 at temperatures above critical temperatures (243-263 K) that depended oil the co-ligands.
