C alytic activation of the Si-N bond. Although such reactions are known to occur in some instances in the absence of catalysts,'S a search of the literactwe did not reveal any examples of catalytic activation of the Si-N bond, despite the fact that silicon compounds have been shown to participate in a wide variety of catalytic reactions. A review by Curtis3 indicates that one can catalytically cleave and reform (redistribute) silicon-oxygen, silicon- ...
