Synthesis and characterization of novel neutral σ-alkynylcarbonylnitrosyl molybdenum(0) and tungsten(0) complexes. Crystal structure of [Mo(C≡CnPR)(CO) 2(dppe)(NO)] [dppe = 1,2-bis(diphenylphosphino) ethane]

σ-Alkynyl dicarbonyl complexes [M(C≡CR)(CO)2(dppe)(NO)] (M = Mo, R = H, tBu, nPr, iPr, Ph, CH2OCH3, SiMe3; M = W, R = H, tBu, nPr) have been prepared by reaction of mer-[M(CO)3(dppe)(NO)][BF4] with an equimolar amount of the acetylide salt M′C≡CR (M′ = Li, Na). The complexes [M(CO)2(NCMe)(dppe)(NO)] [BF4] (M = Mo, W) and [Mo(CO)(NCMe)2(dppe)(NO)][BF4] obtained by reaction of mer-[M(CO)3(dppe)(NO)][BF4] with acetonitrile are suitable precursors for the synthesis of the complexes [M(CO)2(dppe)(PR3)(NO)][BF4] (M = Mo, W, PR3 = PMe3, PMe2Ph) and [M(CO)(NCMe)(dppe)(PR3)(NO)][BF4] (PR3 = PMe2Ph, PPh3, P(OPh)3). The reaction of [Mo(CO)2(NCMe)(dppe)(NO)][BF4] with NaS(o--C6H4Me) yields the neutral complex [Mo{S(o-C6H4Me)}(CO)2(dppe)(NO)]. The crystal structure of [Mo(C≡CnPr)(CO)2(dppe)(NO)] has been determined by X-ray diffraction methods. The Mo atom displays a distorted octahedral coordination involving the N and C atoms of the nitrosyl and the alkynyl ligands in the apical positions and the P atoms from the dppe chelating ligand and two C atoms from terminal carbonyl groups in the equatorial positions.
