characterization, and reactivities of the new stable mono- and cis-disubstituted Group 14 metal(II) chromium and tungsten carbonyl complexes (salen)MM′(CO)5 [salen = 2,2′-N,N′-bis(salicylidene)ethylenediamine; M′ = Cr, M = Ge (4), Sn (5), Pb (6); M′ = W, M = Ge (7), Sn (8), Pb (9)] and [(salen)M]2=M′(CO)4 [M′ = W, M = Ge (10), Sn (11), Pb (12); M′ = Cr, M = Sn (14), Ge (15)] are described. Complexes 4–9 were
新型稳定的单和顺式二取代第 14 族金属(II)铬和钨羰基配合物(salen)MM'(CO)5 [salen = 2,2'-N,N'-双(水杨基)乙二胺;M' = Cr, M = Ge (4), Sn (5), Pb (6); M' = W, M = Ge (7), Sn (8), Pb (9)] 和 [(salen)M]2=M'(CO)4 [M' = W, M = Ge (10),锡 (11), 铅 (12); M' = Cr, M = Sn (14), Ge (15)] 进行了描述。通过用稳定的二价物质 (salen) MII [M = Ge (1), Sn (2), Pb (3)] 处理 M'(CO)5 · THF 中间体,可以高产率地获得配合物 4-9。(salen)MII 和 M'(CO)6 的混合物的直接照射导致形成单取代化合物 4-9 以及双取代物质 10-12、14 和 15,其比例取决于
