The reaction of the anion of methymethoxycarbenotungsten with enol ethers leads, after protonation, to new alkylidene complexes which result from the pericyclic addition of the two aforementioned species. Treatment of these new complexes with base gives after alcohol elimination the new vinylalkylidene complexes of tungsten.
质子化后,甲氧基甲碳烯基
钨酸的阴离子与烯醇醚的反应导致新的亚烷基络合物,这是由于上述两种物质的环加成所致。用碱处理这些新的配合物,在消除醇后得到
钨的新的
乙烯基亚烷基配合物。
