Abstract A series of substituted-cyclopentadienyl molybdenumallylderivatives has been prepared by reacting (η 3 -C 3 H 5 ) 3 MoCl with substituted-cyclopentadienyl and -indenyl alkali metal salts. In general, the isolated products are of the type Cp′Mo(η 3 -C 3 H 5 ) 2 and in three cases this has been confirmed by crystal structure determinations. Spectroscopic evidence suggests that at low temperatures
摘要通过使(η3 -C 3 H 5)3 MoCl与取代的环戊二烯基和-茚基碱金属盐反应,制备了一系列的取代环戊二烯基钼烯丙基衍生物。通常,分离出的产物为Cp'Mo(η3 -C 3 H 5)2类型,这在三种情况下已通过晶体结构测定得到证实。光谱证据表明,在低温下还形成了具有Cp'Mo(η3 -C 3 H 5)2(η1 -C 3 H 5)组成的化合物。与芴基钾的反应是反常的:NMR光谱和晶体结构确定表明,产物(η3-芴基)Mo(η3 -C 3 H 5)3包含四个与金属不对称键合的η3-烯丙基原子。
