摘要：

Treatment of the tungsten compounds [W(= CR) Br(CO)4] (R = C6H4Me-4, C6H4OMe-2, or C6H3Me2-2,6) in tetrahydrofuran with the salts K[HB(3,5-Me2pz)3][HB(3,5-Me2pz)3 = hydrotris(3,5-dimethylpyrazol-l-yl)borate], K[HB(3-Phpz)3] [HB(3-Phpz)3 = hydrotris(3-phenylpyrazol-1-yl)borate] and K[HB(pz)3][HB(pz)3 = hydrotris(pyrazol-1-yl) borate], affords, respectively, the complexes [W(= CC6H4Me-4)(CO)2{HB(3,5-Me2pz)3}], [W(= C6H4Me-4)(CO)2{HB(3-Phpz)3}] and [W(= CR)(CO)2{HB(pz)3}] (R = C6H3Me2-2,6 or C6H4OMe-2). Protonation of the compound [W(= CC6H4OMe-2)(CO)2{HB(pz)3}] with HBF4.Et2O gives the salt [W{= C(H)C6H4OMe-2}(CO)2{zHB(pz3}][BF4]. The NMR data for the new complexes are reported and discussed.
