Process for the preparation of TCD-monenal

摘要

In preparation of 8(9)-formyl-tricyclo[5.2.1.0{2.6}]dec-3-ene (TCD-monenal) by hydroformylation of dicyclopentadiene (DCP) at 70-150[deg]C and 0.5-10 MPa in a heterogeneous reaction system using an aqueous solution containing Group VIII transition metal compounds complexed with water-soluble organic phosphorus(III) compounds, the phosphorus compounds are metal salts of sulfonated triarylphosphines or aryldiphosphines. The preparation of 8(9)-formyl-tricyclo[5.2.1.02>.6]dec-3-ene (TCD-monenal) by hydroformylation of dicyclopentadiene (DCP) at 70-150[deg]C and 0.5-10 MPa in a heterogeneous reaction system involves using an aqueous solution containing Group VIII transition metal compounds complexed with water-soluble organic phosphorus(III) compounds. The phosphorus compounds are metal salts of sulfonated triarylphosphines of formula (I) or aryldiphosphines of formulae (II) or (III); [Image] [Image] [Image] Ar1>-Ar3>6-14 C aryl; Y1-Y3linear or branched 1-4C alkyl, Cl, Br, OH, CN, NO2 or NR1>R2>; R1>, R2>H or linear or branched 1-4 C alkyl; m1-m30-5; n1-n30-3 and 1 or more in at least one case; n4- n80 or 1, such that (II) contains up to 6 SO3M groups and (III) contains 4-8 SO3M groups; M : Li, Na, K, Mg, Ca or Ba in (I) and a monovalent metal or the equivalent of a polyvalent metal in (II) and (III).
