A process for producing 2-formyl-1,4-butanediol comprises effecting reaction of 2-butene-1,4-diol with hydrogen and carbon monoxide in the presence of: (a) a rhodium compound, (b) a tris(substituted aryl) phosphite having an electronic parameter, nu -value, of 2,080 to 2,090 cm-1 and a steric parameter, theta -value, of 135 DEG to 190 DEG and being represented by the formula P(OR)3 wherein each of R's, which may be the same or different, represents a substituted aryl group having at least 7 carbon atoms, and (c) a bis (diphenylphosphino) alkane represented by the formula Ph2P-(CH2)n-PPh2 where n n is an integer of 2 to 6, and at a temperature of not more than 80 DEG C.
