Abstract
Polysilylated hydrazines have wide applicability. It is tedious to prepare these compounds by classic means. However, using hexamethyldisilane and 1,2-dimethyl-1,1,2,2-tetraphenyldisilane as counterattack reagents, we synthesized polysilylated hydrazines under alkaline conditions in good to excellent yields. This one-pot method is expedient and more efficient than other procedures. Polysilylated hydrazines were found to react with aldehydes or ketones in the presence of a catalytic amount of trimethylsilyl trifluoromethanesulfonate to give the corresponding hydrazones under anhydrous conditions. © 1988.
