Preparation and Physical Properties of Sulfur Compounds Related to Petroleum. VI. endo-4,7-Methano-cis-2-thiahydrindan and endo-4,7-Ethano-cis-2-thiahydrindan
The hydroformylation of 1-alkenes was efficiently catalyzed by PtCl2–diphosphine–SnX2 systems whose diphosphines were 1,4-bis(diphenylphosphino)butane derivatives with rigid ring skeletons. The effects of the structure of diphosphines, the P/Pt atomic ratio, the sort of tin(II) halide or solvent, the reaction variables, and the structure of olefins on the relative rate and the product distribution

PROBLEM TO BE SOLVED: To provide a process for the carbonylation of ethylenically unsaturated compounds including vinyl esters and a process for the production of 3-hydroxypropanoate esters or 3-hydroxypropanoic acids.SOLUTION: The process comprises reacting the compound with carbon monoxide in the presence of a source of hydroxyl groups and of a catalyst system. The catalyst system is obtainable by combining: (a) a metal of Group 8, 9 or 10 or a compound thereof: and (b) a bidentate ligand of general formula (I): X(X)-Q-A-R-B-Q-X(X).
