Abstract

The reactions of [Ni(NO2)XL2][X = Cl, L =½ dppe (dppe = Ph2PCH2CH2PPh2), PPh3, PPrn3, OPPh3, or NC5H5; X = Br, L =½ dppe or PPh3; X = NO2, L =½ dppe] and trans-[M(NO2)2L2](M = Pd, L = PEt2Ph or PEt3; M = Pt, L = PEt2Ph, PEt3, or PBun3) with carbon monoxide have been examined. The nickel compounds react to produce the corresponding nitrosyl compounds [Ni(NO)XL2] and CO2. The palladium and platinum compounds react with CO to form [M(CO)2L2] complexes and subsequently higher clusters, except for [Pt(NO2)2(PEt3)2] where evidence for the formation of [Pt(NO)(NO2)(PEt3)2] and [Pt(NCO)(NO2)(PEt3)2] has been found. On reaction with dioxygen the compounds [Ni(NO)XL2] afford the nitro-complexes [Ni(NO2)XL2] exclusively, the rate of the reaction depending on L. The compound [Pt(NO)(NO3)(PPh3)2], prepared from the reaction of N2O4 with [Pt(PPh3)4] in toluene, reacts with O2 to produce trans-[Pt(NO3)2(PPh3)2]. In solution, [Pt(NO)(NO3)(PPh3)2] undergoes an intramolecular reaction to form [Pt(NO2)2(PPh3)2]. The complex [Pt(N2O2)(PPh3)2] reacts with [NO][PF6] to form [{Pt(PPh3)2}2N2O2][PF6]2.
