METHOD OF PREPARING BIMETALLIC RUTHENIUM/TIN CATALYST, THUS PREPARED BIMETALLIC CATALYST, AND METHOD OF PREPARING ALDEHYDES AND THEIR DERIVATIVES

摘要

organic synthesis catalysts. SUBSTANCE: catalyst contains carrier and metal phase including partially intermetallic compound being at least partly in the form of Ru3Sn7, covering at least part of indicated carrier. Catalyst is prepared by depositing, onto carrier, ruthenium/tin complex, wherein oxidation state of ruthenium is equal to 4 and its coordination number to 6, said complex being depicted by general formula [Ru(SnX3)6-nXn]4-, wherein X denotes halogen atom (preferably chlorine or bromine), n is number between 0 and 2 (preferably 1), and cation A is hydrogen, after which complex is subjected to reduction. EFFECT: enabled formation of homogenous catalyst under industrial-scale conditions. 31 cl, 3 ex
