Making use of two seat diphosphine compositions which possess the building a bridge basis which includes the SP2 mixed carbon atom which is connected to the phosphorus atom the method to hydro formyl of converting the ethylene characteristic unsaturated compound

摘要

Under existing of catalyst system of specification, the ethylene characteristic unsaturated compound which is possible to be substituted by reacting with carbon monoxide and hydrogen to hydro formyl the method of converting. As for catalyst system of specification, (a) VIII family metal cation source and, (b) the diphosphine ligand which possesses general system X¹ -r-x2 (in formula, X¹ and as for X^{2 the} annular basis which at least possesses five which is possible to be substituted by independence respectively ring atoms is displayed, one of the ring atoms is the phosphorus atom, as for R, connected to each phosphorus atom the building a bridge basis of two value which is possible to be substituted is displayed with the sp2 mixed carbon atom) with, (in the aqueous solution of c) 18C measuring, the acid of pKa3, or the salt which then was induced and, (d) it includes with halide anionic source. Furthermore, two seat diphosphine of several specification which are used with this method are stated.
