摘要：The three-component reactions of the 16 electron half-sandwich complex CpCo(S2C2B10H10) (Cp: cyclopentadienyl) with ethyl diazoacetate (EDA) and terminal allenes at ambient temperature lead to compounds 1 and 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 (H-1, B-11, C-13), mass spectra, IR spectroscopy and elemental analysis, and their solid-state structures were further characterized by X-ray structural analysis.
