Notes:
The Wittig reaction of aromatic aldehydes with 1,2-bis-(ethoxycarbonyl) ethylidene triphenyl phosphorane (1) furnished oily mixtures of the two diastereomeric products (E) and (Z) (2). Alkaline hydrolysis of the diesters followed by fractional crystallization affords the corresponding (E)-isomers (3) and (Z)-isomers (4). The structures of these products are supported by elemental analysis, i.r., u.v., n.m.r. and its chemical behaviour.
