Introduction It is well known that organometallic hydrides of rare earth metals are the catalysts and reducing reagents for the catalysis polymerization of alkenes and the catalysis hydrogenation of alkenoalkynes. There are four methods for the syntheses of organometallic hydrides of rare earth metals:(1) the thermal atomization of metals, i.e., the interaction of a rare earth metal with alkenes with a terminal alkyne;(2) the Ln—Cσ bond is broken with H_2;(3) metal-
