Abstract:
A method for producing an aldehyde, comprising:reacting an olefinic compound with carbon monoxide and hydrogen in the presence of a catalyst containing a metal of Group 8 to 10 and a trivalent organic phosphorus compound, thereby producing said aldehyde;wherein said trivalent organic phosphorus compound is a phosphonite compound selected from the group consisting of a compound of formula (I), a compound of formula (II), a compound of formula (III), a compound of formula (IV) and a compound of formula (V);wherein formula (I) is: ##STR49##whereinZ.sup.1 is a substituted or unsubstituted hydrocarbon group;each of X.sup.1 and Y.sup.1 is independently a substituted or unsubstituted bivalent hydrocarbon group;Q.sup.1 is a substituted or unsubstituted methylene group; andm is 0 or a positive integer;wherein formula (II) is: ##STR50##whereinX.sup.2 is a substituted or unsubstituted hydrocarbon group;each of Y.sup.2 and Z.sup.2 is independently a substituted or unsubstituted bivalent hydrocarbon group;Q.sup.2 is a substituted or unsubstituted methylene group; andn is 0 or a positive integer;wherein formula (III) is: ##STR51##whereinX.sup.3 is a substituted or unsubstituted hydrocarbon group; and each of Y.sup.3 and Z.sup.3 is a substituted or unsubstituted aromatic hydrocarbon group;wherein formula (IV) is: ##STR52##whereineach of X.sup.4, X.sup.5, X.sup.6 and X.sup.7 is independently a substituted or unsubstituted bivalent hydrocarbon group;Q.sup.3 is a substituted or unsubstituted bivalent hydrocarbon group;each of Q.sup.4 and Q.sup.5 is a substituted or unsubstituted methylene group; and each of m1 and m2 is 0 or a positive integer; andwherein formula (V) is: ##STR53##whereineach of X.sup.8, X.sup.9, X.sup.10 and X.sup.11 is a substituted or unsubstituted hydrocarbon group; andQ.sup.6 is a bivalent organic group.
