The reaction of triisopropyl- or tricyclohexylhalosilanes with silver salts gives the corresponding silyl nitrites and silyl nitrates. The insertion reaction of sulfur trioxide or dichlorocarbene into the silicon hydrogen bond of triisopropylsilane and tricyclohexylsilane yields the sulfates and the dichloromethyl derivatives, respectively.
