摘要:半夹芯式碳硼烷16e金属有机化合物Cp Co(S2C2B10H10)与重氮乙酸乙酯及联烯在室温下反应,生成化合物1和2。在化合物1和2中,一分子重氮乙酸乙酯与一分子联烯以头-头方式插入Co-B键之间使碳硼烷B(3)/(6)位发生B-H键活化生成B-C键,另有一分子重氮乙酸乙酯使Co-S断裂形成硫叶立德。分别采用红外、核磁、元素分析、质谱和单晶X射线衍射等表征方法对化合物1和2进行了结构表征。
The three-component reactions of the 16 electron half-sandwich complex Cp Co(S2C2B(10)H(10))(Cp:cyclopentadienyl) with ethyl diazoacetate(EDA) and terminal allenes at ambient temperature lead to compounds 1and 2.In 1 and 2, one EDA and one allene are inserted into Co-B bonds in a head-to-head mode making the hydrogen atom of the B(3)-H bond transform into the middle carbon of allene.One EDA molecule is also inserted into a Co-S bond to form a sulfide ylide.The new compounds 1 and 2 were characterized by NMR(1H,11 B,13C),mass spectra, IR spectroscopy and elemental analysis, and their solid-state structures were further characterized by X-ray structural analysis.
