ABSTRACT:
It is provided a process for industrially advantageously producing a branched aldehyde represented by the formula; ##STR1## represents an acyloxymethyl group represented by --CH.sub.2 OY' (where Y' represents an acyl group of two or more carbon atoms), cyano group or an alkoxycarbonyl group! which is useful as an intermediate for pharmaceuticals and agricultural chemicals, comprising subjecting an olefinic compound represented by the following formula; ##STR2## (wherein Y and X are the same as defined above), to the reaction with hydrogen and carbon monoxide in the presence of a rhodium compound and a tertiary organic phosphorus compound with an electronic parameter (.upsilon.-value) of 2080 to 2090 cm.sup.-1 or with a steric parameter (.theta.-value) of 150 to 180.degree..
