资源简介:

Photolysis of W(CO)6 in the presence of Ph2SiH2 in n-heptane leads to the formation of the first μ-silyleneditungsten complex (μ-SiPh2)W2(CO)10. The molecular structure of the new silylene compound was established by single-crystal X-ray diffraction studies and characterized by IR and 1H, 13C{1H}, and 29Si{1H} NMR spectroscopy. In CDCl3 solution the silylene compound reacts with bicyclo[2.2.1]hept-2-ene to give W(CO)5(η2-C7H10) and 1,3-cyclopentylenevinylene.
