    Abstract: 1314890 Bis-monocarboxylic esters of 3- formyl butanediol-1,2 BADISCHE ANILIN- & SODA-FABRIK AG 8 Sept 1970 [9 Sept 1969] 42873/70 Heading C2C The invention comprises compounds of the Formula I where R is an alkyl C 1-18 radical or a phenyl radical optionally substituted by one or two alkyl C 1-4 , alkoxy C 1-4 , chlorine or nitro groups, They and the compound of Formula I wherein R = H may be prepared by reacting the appropriate bis-ester of butene-1-diol-3,4 with carbon monoxide and hydrogen in the presence of a carbonyl complex of rhodium at elevated temperature, e.g. 60-120‹ C. and super atmospheric pressure e.g. 300-1200 atmospheres. 3 - Formylcrotylbenzoate is prepared by the process described above and without isolating the bis-ester eliminating benzoic acid therefrom using sodium acetate.
