Selective Cleavage of Dimethylhydrazones to the Carbonyl Compounds Using Silica Gel and its Application in the Synthesis of (Z)-9-Tetradecenyl Acetate

All articles of this category A new method for the selective hydrolytic cleavage of dimethylhy- drazones consists of treatment of the hydrazones with silica gel (pH 6.80) in wet tetrahydrofuran. Utilizing this method as one of the key steps, ( Z )-9-tetradecenyl acetate, the pheromone of Spodoptera frugiperda , was synthesized.
