共役ジエンのカルボニル化方法

Japanese Patent JP2007502315

A

A process for the carbonylation of a conjugated diene, which involves reacting the conjugated diene with carbon monoxide and a co-reactant having a mobile hydrogen atom in the presence of a catalyst system including: (a) a source of palladium; and (b) a bidentate diphosphine ligand of formula II, R¹R²>P¹-R³_m-R-R⁴_n-P²5R⁶ (II) wherein P¹ and P² represent phosphorus atoms; R¹, R², R⁵ and R⁶ independently represent the same or different optionally substituted organic radical containing a tertiary carbon atom through which each radical is linked to the phosphorus atom; R³ and R⁴ independently represent the same or different optionally substituted methylene groups; R represents an organic group having the bivalent bridging group C¹-C² through which R is connected to R³ and R⁴; m and n independently represent a natural number in the range of from 0 to 4, wherein the rotation about the bond between the carbon atoms C¹ and C² of the bridging group is restricted a temperature in the range of from 0° C. to 250° C., and wherein the dihedral angle between the plane occupied by the three atom sequence composed of C¹, C² and the atom directly bonded to C¹ in the direction of P¹, and the plane occupied by the three atom sequence C¹, C² and the atom directly bonded to C² in the direction of P², is in the range of from 0 to 120°; and (c) a source of an anion.
