Revised Date: 30 June 1998

4-Chlorophenyl acetaldelyde reacting with T-triazolylpinacolone in the presence of KF/Al₂O₃/PEG4000 will produce 85% vinyltriazolyl ketone(Ⅱ) with E/Z =0.65; Ⅱ is then isomerized by light to a yield of 92% E-Ⅱ with E/Z ≥99/1. It is then reduced in the presence of certain charge transfer catalyst V by KBH₄ to 92% Uniconazole-P with ee of 30%.
