presence of acetonitrile. Hydridoruthenium(II) complexes [(η6-C6H5XCH2PtBu2-κ-P)RuHCl] 13, 14, [RuHCl(H2)(L)2] 15 (L = 1), 16 (L = 2) and [RuHCl(CO)(2)2] 17 could be prepared from RuCl3·3H2O and 1 or 2 in the presence of NEt3 under reductive conditions. Insertion, substitution and addition reactions of compound 17 led to the formation of [Ru(CHCH2)Cl(CO)(2)2] 18, [RuHF(CO)(2)2] 19, and [RuHCl(CO)2(2)2]

The reaction of either [RhCl(C8H14)(2)](2) or [RhCl(C2H4)(2)](2) with tBu(2)PCH(2)CH(2)C(6)H(5) (3) affords at room temperature the five-coordinate arylhydridorhodium(III) complex 4, the molecular structure of which has been determined by X-ray crystallography. The C-H metalation is completely reversible, as is shown by the formation of trans-[RhCl(CO)(3)(2)] from 4 and CO. Compound 4 also reacts with PhC=CH, H-2, and AgPF6 to give products 7-9 containing the intact phosphine ligand 3.

(10) with the new alkyldiisopropylphosphines iPr2P(CH2)nC6H5 (8, n = 2; 9, n = 3), which were prepared from HPiPr2 and C6H5(CH2)nBr in the presence of ammonia, in the molar ratio of 1:1 gave the half-sandwich type complexes [η6-C6H5(CH2)nPiPr2-κ-P}Rh(C8H14)]PF6 (11, 12). They afforded upon treatment with a second equivalent of 8 or 9 the bis(phosphine) compounds [η6-C6H5(CH2)nPiPr2-κ-P}C6H5(CH2)nPiPr2-κ-P}Rh]PF6
