  摘要：

  Reaction of Os3(CO)10(NCMe)2 (1) with 1-hydroxybenzotriazole (2) gave the hydrido complex (mu-H)Os3(CO)10(mu2-(2,3-eta2)-NNN(O)C6H4) (3) in 60% yield; reaction of isocyanide complexes Os3(CO)10(CNR)(NCMe) (4: R = n-Pr, CH2Ph) with 2 gave the bridging aminocarbyne products Os3(CO)10(mu2-(2,3-eta2)-NNN(O)C6H4)(mu2-eta1-C=NHR) (5 and 6). The O-H bond of the hydroxybenzotriazole ligand was cleaved in these reactions to afford complexes 3, 5, and 6, which contained an N-oxide moiety. Complexes 5a and 6a as well as 5b and Ob were regioisomers because of the restricted rotation about the C=N double bond in the bridging aminocarbyne. These isomers exhibited different polarities and were separated by chromatography. Results-from single-crystal X-ray diffraction analyses for 3, 5a, and 6b revealed the following data. 3: P2(1)/c; a = 8.629(l) angstrom, b = 9.919(l) angstrom, c = 25.446(2) angstrom; beta = 95.447(9)-degrees, V = 21681(3) angstrom3, Z = 4, R = 2.7%, R(w) = 3.0%. 5a: P2(1)/c; a = 10.4824(6) angstrom, b = 15.76.5(2) angstrom, c = 16.001(3) angstrom; beta = 97.981(9)-degrees, V = 2618.6(6) angstrom3, Z = 4, R = 3.0%, R(w) = 3.7%. 6b: P2(1)/c; a = 9.997(2) angstrom, b = 23.639(4) angstrom, c = 12.636(2) angstrom; beta = 111.37(l)-degrees, V 2780.8(8) angstrom3, Z = 4, R = 2.9%, R(w) = 3.1%. Studies on the structures of 5a and 6b by X-ray methods provided the first evidence indicating the existence of regioisomers with different orientations of the coordinated aminocarbyne group.

  The unique linear triosmium clusters Os3Br(CO)10(CNR)(eta3-C3H5) (2) are prepared by reaction of Os3(CO)10(CNR)(NCMe) with allyl bromide. The reaction rate is faster in CH2-CL2 than in cyclohexane. The oxidative addition of allyl bromide to the triosmium cluster is likely to involve a partial heterolytic metal-metal bond fission pathway, and the coordinated isocyanide ligand plays an important role in determining the regioselectivity and the transformation of allyl bromide in the coordination sphere of the cluster. In the absence of the coordinated isocyanide ligand, complex Os3(CO)11(NCMe) reacts with allyl bromide in CH2Cl2 to afford a similar linear complex Os3Br(CO)11(eta3-C3H5) (4) with a slower rate. Complex Os3Br(CO)10(CNPr)(eta3-C3H5) (2a) crystallized in the triclinic space group P1BAR with a = 10.518(5) angstrom, b = 12.026(2) angstrom, c = 19.116(3) angstrom, a = 89.98(1)-degrees, beta = 90.13(3)-degrees, gamma = 93.23(3)-degrees, V = 2414(1) angstrom3, Z = 4, R = 4.7%, and R(w) = 5.1% for 3810 observed reflections. Both the bromide and the, isocyanide ligands coordinate equatorially at the first Os atom, while the allyl group occupIes an axial and an equatorial site on the third Os metal center in the linear triosmium cluster.

  The nitrile derivatives Os3(CO)10(CNR)(NCMe) (2) have been prepared by the reaction of isocyanide complexes Os3(CO)11(CNR) (1) with Me3NO in the presence of CH3CN. The labile complex 2 on reaction with two-electron donor ligands L (L = CO, PPh3, PMePh2) gives Os3(CO)10(CNR)L (3). Treatment of 2 with propynoic acid (HC=CCO2H) in CH2Cl2 yields the hydrido complexes (mu-H)Os3(CO)10(mu2-OCOC=CH)(CNR) (4); however, complex 2 reacts with propynoic acid in acetonitrile to form complex 4 and the bridging aminocarbyne species Os3(CO)10(mu2-OCOC=CH)(mu2-C=NHR) (5) containing a unique bridging unidentate (mu2-eta1-oxo) carboxylate ligand. Molecular structures of Os3(CO)10(CNPr)(PPh3)(3a) and Os3(CO)10(mu2-OCOC=CH)(mu2-C=NHPr) (5a) have been determined by X-ray diffraction studies. Crystal data are as follows. 3a: P1BAR; a = 11.4611 (14), b = 11.6963 (19), c = 14.9661 (22) angstrom; a = 93.635 (12), beta = 73.633 (11), gamma = 117.325 (11)-degrees; V = 1705.0 (4) angstrom3, Z = 2; R = 4.2%, R(w) = 5.1%. 5a: P2(1)2(1)2(1); a = 9.4241 (23), b = 15.414 (4), c = 15.972 (3) angstrom; V = 2320.2 (9) angstrom3, Z = 4; R = 3.2%, R(w) = 3.5%.
