Abstract
1463923 3 - Acetoxy - 2 - methylpropionaldehyde BAYER AG 22 May 1975 [22 June 1974] 22266/75 Heading C2C The novel compound 3-acetoxy-2-methylpropionaldehyde is prepared by hydroformylation of allyl acetate in the presence of a metal carbonyl which has been prepared in the absence of allyl acetate, and is catalytically hydrogenated to give 3-acetoxy-2-methylpropanol which on treatment with methanol and a base give 2-methyl-1,3-propanediol.
