PRODUCTION OF ALUMINUM-COMBINED RUTHENIUM CARBONYL METAL CLUSTER-COMPLEX

摘要

PROBLEM TO BE SOLVED: To efficiently obtain the subject complex useful as an inexpensive catalyst for hydrosilylation by reacting Ru₃(CO)₁₂ with tris-(acetylacetonato) aluminum, etc., in a specific molar ratio of Ru:Au. ;SOLUTION: Ru₃(CO)₁₂ is reacted with an aluminum compound of the formula Al(X)_a(Y)_3-b (X is ethyl, ethoxy, propoxy or butoxy; Y is acetylacetonato or a 2-4C alkylacetonato ligand; (a) is 0, 1, 2 or 3) [e.g. tris-(acetylacetonato) aluminum] in the specific molar ratio of Ru:Au in the range of (3:1) to (3:7) to give the objective metal cluster complex having a composition formula of the formula [Ru₃(CO)₁₂]_x[Al(X)_a(Y)_3-b]y (the ratio of x:y is (1:1) to (1:7) and is useful as a catalyst for hydrosilylation.;COPYRIGHT: (C)1997,JPO
