Transition-metal complexes containing phosphorus ligands. Part IV. Convenient syntheses of some phosphine (and arsine) halogenonitrosyl derivatives of rhodium and iridium

Abstract

Convenient, single-stage syntheses involving addition of rhodium or iridium halides and N-methyl-N-nitrosotoluene-p-sulphonamide to a solution of the appropriate phosphine (or arsine) in a boiling alcoholic solvent have been used to prepare a selection of the halogenonitrosyl complexes, MX2(NO)(PR3)2 and MX2(NO)(AsPh3)2(M = Rh or Ir; X = Cl, Br, or I; R = alkyl, aryl, or mixed alkyl aryl). A mechanism for the nitrosyl formation involving rhodium(III) and iridium(III) hydrides, MX2H(PR3)3, as intermediates is discussed. Use of pentyl nitrite as a source of nitrosyl ligands in these reactions is also reported.
