摘要：

The spectroscopic and structural characteristics and the relative reactivity of several Tp(Ms)Cu-(olefin) (olefin = ethylene, 1, 1-hexene, 2, ally! ethyl ether, ace, 3, cyclohexene, 4, and styrene, 5) complexes bearing the bulky hydrotris(3-mesitylpyrazolyl)borate ligand have been examined. Experimental data, including an unusual high-field chemical shift in the H-1 and C-13 NMR spectra, and DFT theoretical calculations support the proposal that the copper-olefin linkage is mainly sustained by sigma-donation, lacking a substantial degree of pi-back-donation.
