A series of new water soluble and stable organometallic compounds is reported, and the peculiar role of water in their formation and stabilization is documented together with their catalytic properties in aqueous solution. The complex fac-Ru(OCOCF(3))(2)(CO)(3)(H(2)O) (1) constitutes the entry to a new type of aqueous organometallic chemistry. The substitution of trifluoroacetato ligands by H(2)O yields
报道了一系列新的水溶性和稳定的有机金属化合物,并且记录了水在其形成和稳定中的独特作用以及它们在水溶液中的催化性能。复杂的fac-Ru(OCOCF(3)(2)(CO)(3)(H(2)O)(1)构成了一种新型的水性有机金属化学物质。H(2)O取代三氟乙酰基配体产生[fac-Ru(CO)(3)(H(2)O)(3)](2+)(2),作为四氟硼酸酯衍生物分离,第一个结构表征仅带有CO和H(2)O配体的复合物。在水中,2受到溶剂的亲核攻击,产生[fac-Ru(COOH)(CO)(2)(H(2)O)(3)](+)(3),然后将CO(2)消除为给出[fac-RuH(CO)(2)(H(2)O)(3)](+)(4),氢化钌(II),不含15族供体大分子配体,对强酸稳定。4将乙烯插入水中,得到[fac-Ru(C(2)H(5))(CO)(2)(H(2)O)(3)](+)(5),一种非常惰性的烷基络合物插入一氧化碳
