STUDY ON PHASE TRANSFER CATALYTIC WITTIG REACTION
Abstract:
This paper describes the PTC Wittig reaction of ω-hydroxyl alkanyl triphenyl phosphoniurn bromide (Ph3P+(CH)2OHBr,n=10,11) and aliphatic aldehydes(n-hexanal,n-pcntanal) with different solvents and bases. The optimum reaction conditions which can give high yield (80%) and good isomer ratio (Z:E=90:10)are reported. The method appeared convcnient for synthesizing insect sex pheromones.
