  • Process for producing .beta.,.gamma.-unsaturated aldehyde
    Patent number: 4196151
    Abstract: Two molecules of mono-substituted acetaldehyde having the following general formula (I) and one molecule of organic halide having the following general formula (II) are reacted in an alkaline aqueous solution in the presence of a phase transfer catalyst whereby a .beta.-.gamma.-unsaturated aldehyde having the general formula (III) as shown in the following reaction scheme (A) is obtained directly from the monosubstituted acetaldehyde without forming an .alpha.,.beta.-unsaturated aldehyde ##STR1## wherein R.sub.1 is straight chain or branched chain alkyl, alkenyl, cycloalkyl or aryl, R.sub.2 is allyl, substituted allyl, propargyl, substituted propargyl, benzyl or substituted benzyl, and X is halogen.
