to Cp*TaCl4 (1; Cp* = η5-C5Me5) at −40 °C, followed by mild pyrolysis with excess BH3·THF, results in the formation of the μ-acyl complex (Cp*Ta)2B4H8(μ-η2-COCH3) (2). The title compound represents a novel class of μ-acyl complexes in which the bicapped-tetrahedral unit (Cp*Ta)2B4H8 is bridged by a μ-η2-COCH3 acyl ligand.
加入的LiBH的4 ·THF与CP * TACL 4(1 ;的CP * =η 5 -C 5我5)在-40℃,接着热解温和用过量的BH 3 ·THF,导致μ的形成酰基络合物(CP * TA)的2乙4 ħ 8(μ-η 2 -COCH 3)(2)。标题化合物代表了一类新型μ酰基复合物,其中所述双帽四面体单元(CP * TA)的2乙4 ħ 8由μ-η桥接2 -COCH 3酰基
配体。
