| Abstract: |
Synthesis of
dioxadiazasilamacroheterocycles is described. The key step involves the initial
synthesis of symmetrical hydroxyl-functionalized chiral salen ligand, N,N′-bis(2-hydroxyacetophenonylidene)-1,2-diaminocyclohexane followed by sequential deprotonation with NaH to form dianion
intermediate in situ, which reacts
with diorganodichlorosilanes to furnish desired heterocycles. The products have
been characterized by satisfactory elemental analyses and spectral (IR, 1H,
13C,
29Si NMR and mass) studies.
