Abstract
A practical and efficient method for the preparation of silaheterocycles is described. The key step involves the initial formation of symmetrical chiral ditopic ligand, N,Nβ²β1,2βcyclohexylenebis(salicylideneimine) followed by sequential deprotonation with NaH to form dianion intermediate, which reacts with diorganodichlorosilanes to furnish dibenzodioxadiazasilamacrocycles. The products were characterized by satisfactory elemental analyses and spectral (IR, ^1^H, ^13^C, ^29^Si NMR, and Mass) studies. Β© 2008 Wiley Periodicals, Inc.
