| Description |
5-ethoxycarbonyl-2-(alkyloraryl)-4-(alkyloraryl)-2-cylopenten-1-one and 2-ethoxycar-bonyl-5-(alkyl or aryl)-3-(alkyl or aryl)-2- cyclopenten-1-one derivatives and ethyl-6-(alkyl or aryl)-3-(alkyl or aryl)-6-oxo-2,4-hexadienoate derivatives have been prepared by a single step reaction between [2-ethoxy-3-(4-subsituted phenyl)-2-propenylidene triphenyl phosphonium bromides and bifunctional carbonyl compounds e.g glyoxal in presence of a base. The mechanism of the formation of the products is also proposed.
Key words: Wittig Reaction, Triphenyl phosphonium bromide, Hexadienoate, Cyclopentanoate
