    Abstract: The present invention relates to a process for the hydroformylation of compounds of the formula (I), where X is C, P(Rx), P(O—Rx) S or S(═O), where Rx is H, alkyl, cycloalkyl, heterocycloalkyl, aryl or hetaryl; A is a divalent bridging group having from 1 to 4 bridging atoms; and R1 is H, alkyl, alkenyl, alkynyl, cycloalkyl, heterocycloalkyl, aryl or hetaryl; or salts thereof; in which the compound of the formula (I) is reacted with carbon monoxide and hydrogen in the presence of a catalyst comprising a complex of a metal of transition group VIII with a compound of the formula (II), where Pn is a pnicogen atom; W is a divalent bridging group having from 1 to 8 bridging atoms; R2 is a functional group capable of forming an intermolecular, noncovalent bond with the group —X(═O)OH; R3, R4 are each alkyl, cycloalkyl, heterocycloalkyl, aryl or hetaryl; a, b, c are each 0 or 1; and Y1, Y2 and Y3 are each O, S, NRa or SiRbRc; and also compounds of the formula (II.a), where W′ is a divalent bridging group having from 1 to 5 bridging atoms between the flanking bonds, Z is O, S, S(═O), S(═O)2, N(RIX) or C(RIX)(RX); and RI to RX are each, independently of one another, H, halogen, nitro, cyano, amino, alkyl, etc.; or two radicals RI, RII, RIV, RVI, RVIII and RIX together represent the second part of a double bond.
