Metal alkoxides - models for metal oxides. 6. The linking of alkyne and nitrile fragments at ditungsten centers. Preparation and characterization of W2(O-tert-Bu)6(CHCHC(Ph)N), W2(O-iso-Pr)7(CH2CHC(Ph)N), W2(OCH2-tert-Bu)6(N(CMe)4N)(py), and W2(O-iso-Pr)7(NHC(Me)CHCHC(Me)N)
The remarkable role of steric factors in the reactions of alkynes (HCCH and MeCCMe)with ditungsten hexa-alkoxides: crystal and molecular structures of W2(OPri)6(py)2(µ-C2H2), W2(OCH2But)6(py)2(µ-C2Me2), and W2(OPri)6(µ-C4R4)(C2R2), where R = H and Me (py = pyridine)
