Abstract: PROBLEM TO BE SOLVED: To obtain the subject complex suitable for the coordination polymerization of various monomers by reacting a mononuclear metal complex in the presence of hydrogen under a specific pressure and at a specific temperature. SOLUTION: A mononuclear metal complex expressed by formula I [M is Sc, Y, La, etc.; R is H, a halogen, a 1-20C alkyl or the like; Z is SiR'2(R' is a 1-20C alkyl or the like), O or the like; (m) is 1, 2; X is O, S or the like; L is a low molecular weight Lewis base; and (n) is 0 or l] is reacted in the presence of hydrogen, at 1.5-100 bar pressure and 0-100 deg.C temperature, preferably in an inactive solvent such as n-pentane or the likes to obtain a complex expressed by formula II, e.g. bis[tetramethylcyclopentadienyl(tert-butylamide) dimethylsilylyttrium hydride]. The side complex is useful as a catalyst for (co)polymerizing polar monomers.

Abstract: PROBLEM TO BE SOLVED: To obtain a new semi-sandwich complex of a mononuclear bis- alkylmetal capable of obtaining a uniform high purity product in an industrial scale by coordinating and polymerizing various monomers such as a polar olefinic unsaturated monomer, lactone, etc. SOLUTION: This semi-sandwich complex of a non-cross-linked mononuclear bis-alkylmetal having a polymerization activity based on a rare earth metal, is expressed by the formula (M is scandium, yttrium, lanthanum, or lanthanide; R is H, a halogen, a 6-15 aryl or the like; R' and R" are each a 1-20C alkyl, a 3-10C cycloalkyl, a 6-15C aryl or the like; L is a low molecular weight organic compound of a Lewis base; (m) is 0-4; (n) is 0, 1), e.g. [(trimethylsilyl) cyclopentadienyl]yttrium. Further, the compound of the formula is obtained by reacting M[CH2-n(SiR"3)1+n]3(L)2 with CpR4(H)(SiR'3) in an inert solvent.
