Utilization of industrial waste materials. Part 20. Stereoselective cycloaddition of silylenes and a disilene to an enantiomerically pure cyclic ketimine derived from an industrial waste material

A new enantiomerically pure aromatic cyclic ketimine with two stereogenic centres derived from an industrial waste material has been used as a reactant in novel stereoselective cycloadditions of silylenes and disilenes. The products obtained are chiral non-aromatic organosilanes.
