Patent ID: 8822714

Claim:
A preparation method of organic-transition metal hydride comprising the following steps: a) preparing a complex reducing agent composition by reacting alkali metal, alkali earth metal or a mixture thereof with (C10-C20) aromatic compound in aprotic polar solvent; and b) preparing organic-transition metal hydride by reacting the prepared complex reducing agent composition and organic-transition metal halide; wherein the organic-transition metal hydride is selected from those compounds represented by formula 3 and the organic transition metal halide is selected from those compounds represented by formula 4 B 2 -(M 2 H a ) b Formula 3 B 2 -(M 2 X a ) b Formula 4 (In formula 3 and formula 4, B 2 should be selected from the group consisting of cyclopentadiene, cyclopentadiene derivatives, and fused ring compounds containing cyclopentadiene or cyclopentadiene derivatives, B 2 can be replaced with one or more substituents selected from the group consisting of —NO 2 , —NO, —NH 2 , —R 1 , —OR 2 , —(CO)R 3 , —SO 2 NH 2 , SO 2 X 1 , —SO 2 Na, —(CH 2 ) k SH and —CN, and in that case, R 1 -R 3 of the substituent can be selected from the group consisting of straight or branched (C1-C30) alkyls and (C6-C20) aryls, respectively; X 1 is a halogen element, and k is an integer of 0-10, M 2 is one or more transition metal elements having the valence of at least 2, a is an integer that a valence of M 2 −1, and b is an integer of 1-10).
