A method for producing an aldehyde, which comprises reacting an olefinic compound with carbon monoxide and hydrogen in the presence of a Group VIII metal compound and an organic phosphite compound to produce a corresponding aldehyde, wherein an organic phosphite compound of the formula (I): P(OR1)(OR2)(OR3) (I> wherein each of R1 and R2 which may be the same or different, is a 2-naphthyl group which may have a substituent, provided that at least one of R1 and R2 is a substituted 2-naphthyl group of the formula (II): <CHEM> wherein R4 is a C1-30 organic group, and each of R5, R6, R7, R8 and R9 which may be the same or different, is a hydrogen atom or an organic group, and R3 is 1/ &cir& a 2-naphthyl group which may have a substituent, 2/ &cir& a phenyl group which may have a substituent, or 3/ &cir& an alkyl group which may have a substituent, is used as said organic phosphite compound. |
