Desilatranation of 1-organylsilatranes

Reaction of phenyltrifluorosilane with 1-hydro- and 1-ethoxysilatranes proceeds with the cleavage of the F–Si bond and the formation of 1-fluorosilatrane. Under the action of alkylsilatranes also the cleavage of C–Si bond is observed with the formation of a minor product, 1-fluorosilatrane.
