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.
