For the thermal dimerization of the dienes 1 and 4 a parallel increase in facial selectivity and reaction rate is observed on going from the (E)-alkyl-aryl dienes 1h-m and the (Z)-dienes 4a, b to the (E)-aryl-aryl dienes 1a-f.This phenomenon is inte

The (E)-dienes 1a - p were prepared in >98percent purity by dehydrative decarboxylation of the corresponding 4,5-unsaturated 3-hydroxycarboxylic acids 3 with dimethylformamide dimethylacetal (11).The (Z)-isomers 6a - m were obtained by stereouncontrolled
