Synthesis and Characterization of Dibenzodioxazasiladecines

Abstract

The reaction of N‐(2‐hydroxymethylphenyl)salicylideneimine with sodium hydride in dry toluene at −4°C produces 1,9‐remote dianion. The cyclization of this dianion with diorganodichlorosilanes affords dibenzodioxazasiladecines in good yields. The products were characterized by satisfactory elemental analyses and spectral (IR, ¹H, ¹³C, and ²⁹Si NMR and mass) studies.
