Complexes of 1,3,5-triphenyl-1,3,5-diazaphosphorinane with Pt(II), Co(II), Ni(II), AND Cu(I) salts
摘要:
1,3,5-Triphenyl-1,3,5-diazaphosphorinanes form 2:1 complexes with Pt(II), Co(II), Ni(II), and Cu(I). P-31 NMR spectroscopy indicated that Pt, Co, and Ni are coordinated at the phosphorus atoms, while Cu(I) is coordinated at the nitrogen atoms.

as overpotentials are decreased. Catalytic studies using acids with a range of pK(a) values reveal that turnover frequencies do not correlate with substrate acid pK(a) values but are highly dependent on the acid structure, with this effect being related to substrate size. Addition of water is shown to dramatically increase catalytic rates for all catalysts. With [Ni(P(Ph)(2)N(C6H4CH2P(O)(OEt)2)(2))(2)](BF(4))(2)

and trinuclear gold(I) complexes are synthesized by the reactions of gold(I) chloride or tetrahydrothiophenegold(I) chloride with 1,5-di(p-tolyl)-3,7-diphenyl-1,5,3,7-diazadiphosphacyclooctane taken in various ratios. The structures of the synthesized compounds are confirmed by NMR spectroscopy, elemental analysis, and X-ray diffraction analysis (CIF files ССDC nos. 1974032 (I) and 1974031 (II)). Unlike

Reversible binding of H2 is shown for nickelcomplexes yielding the products of dihydrogen heterolytic splitting [NiH(PR12NR22)(PR12NR22H)]2+ (P2N2=1,5-diaza-3,7-diphosphacyclooctane) whose intermediacy in the reaction has been only anticipated so far. With the help of NMR spectroscopy and parahydrogen induced polarization, the formation of [Ni(η2−H2)(PR12NR22)2]2+ complex was detected for the first time
