摘要: In contrast with pi-bonded organometallic compounds of the lanthanides1 and actinides2, which date to mid 1950’s, encompass a large variety ligands3 culminate synthesis bis-(cyclooctatetraenyl)uranium (“uranocene”),4 preparation sigma-bonded lanthanide actinide organometallics is relatively recent. Early attempts prepare simple oganometallic derivatives, such as U(CH3)4 5, Y(C2H5)3, Sc(C2H5)3 6, often resulted in poorly characterized or irreproducible products. Sigma-bonded derivatives both lanthanide7,8 actinide9 elements are now known well characterized.10
