A no. of important synthetic intermediates, trans-alkenols were synthesized by Schlosser-Wittig reaction of (Ph3P+(CH2)nOH Br-(n = 3, 10 and 11) and aliphatic aldehydes. The yields were 35%~85% and the ratio of E/Z were 90.5/9.5~99.8/0.2. The esterification or oxidation of the alkenols gave a series of insect sex pheromones.

Key words: BENZENE P, WITTIG REACTION, ALKANE P, MONOHYDRIC ALCOHOL, INSECT HORMONE, SEX PHEROMONE, ENOLS, ALIPHATIC ALDEHYDES, PHOSPHONIUM COMPOUNDS
