Molecular Defined Molybdenum-Pincer Complexes and Their Application in Catalytic Hydrogenations

A family of low-valent molybdenum complexes, supported by the pincer ligand (iPr2PCH2CH2)2NH, was prepared and characterized. After activation by NaBHEt3 coordination compounds 2 and 3-Cl were found to be suitable catalysts for the hydrogenation of ketones and olefins.

Metallathiirenes. 3.1 thiocarbamoyl and alkoxythiocarbonyl complexes of molybdenum(II) and tungsten(II)

Synthetic routes to thiocarbamoyl (thiocarboxamide) complexes of divalent molybdenum and tungsten are reported: The reaction of fac-[Mo(CO)3(NCMe)3] with N,N-dimethyl thiocarbamoyl chloride (Me2NC(=S)Cl) at low temperature provides a thermally labile intermediate (1) presumed on the basis of subsequent transformations to be [Mo(η2-SCNMe2)-Cl(CO)3(NCMe)]. Reactions of 1 with K[HB(pz)3] (pz = pyrazol-1-yl), NaC5H5, bipy, or tmeda provide the complexes [Mo(η2-SCNMe2)(CO)2{HB(pz)3}] (2), [Mo(η2-SCNMe2)(CO)2(η-C5 H5)] (3), [Mo(η2-SCNMe2)Cl(CO)2(bipy)] (4), and [Mo(η2-SCNMe2)Cl(CO)2(tmeda)] (5), respectively. The complex cis,cis,trans-[Mo(η2-SCNMe2)Cl(CO)2 (PPh3)2] (6) results from the oxidative addition of Me2NC(=S)Cl to [Mo(NCMe)2(CO)2(PPh3)2] and is one of two isomers obtained from the reaction of 1 with PPh3. The complex 2 may also be obtained from reaction of (i) K[Mo(CO)3{HB(pz)3}] with Me2NC(=S)Cl; (ii) [Mo(CO)3(η6-C7H8)] with Me2NC(=S)Cl and K[HB(pz)3]; and (iii) K[HB(pz)3] with either 5 or 6. Sequential treatment of either [Mo(CO)3-(NCMe)3] or [Mo(CO)3(η6-C7H8)] with ClC(=S)OR (R = C6H4Me-4, C6H5) and K[HB(pz)3] provides the complexes [Mo(η2-SCOR)(CO)2{HB(pz)3}] [R = C6H4Me-4 (7a), C6H5 (7b)]. Attempts to prepare a mononuclear thiocarbamoyl complex by addition of elemental sulfur or propene episulfide to the aminomethylidyne complex [Mo(≡CNiPr2)(CO)2{HB(pz)3}] (8) were unsuccessful; however addition of [Fe2(CO)9] to 8 provided the thermally unstable complex [MoFe(μ-CNiPr2)(CO)5{HB(pz)3}] (9), which reacts with sulfur to provide the heterobimetallic bridging thiocarbamoyl complex [MoFe(μ-SCNiPr2)(CO)5{HB(pz)3}] (10). Treating fac-[W(CO)3(NCMe)3] sequentially with Me2NC(=S)Cl and K[HB(pz)3] provided [W(η2-SCNMe2)(CO)2{HB(pz)3}] (11); however replacing Me2NC(=S)Cl with ClC(=S)OC6H4-Me-4 led to [WCl(CO)3{HB(pz)3}] (12).
