Abstract
1,197,467. Preparing substituted 1,4-dienes. UGINE KUHLMANN. 13 Sept., 1967 [14 Sept., 1966], No. 41830/67. Heading C2C. Substituted 1,4-dienes having the Formula I are prepared by pyrolysing a compound of Formula II in which formulµ X is an aldehyde group, or a carboxyl group or derivative thereof, e.g. a nitrile, amide or ester group; R is hydrogen or C 1 to C 4 alkyl; and -D- is a divalent radical derived from a Diels-Alder conjugated diene reactant D. The compounds of Formula II may be prepared by allylating, with a compound of formula wherein Y is halogen or -OH, a compound produced by a Diels-Alder reaction between the diene D and an acrylic compound CH 2 = CH-X.
