Abstract
Silaazacycles (or azasilacycles), containing both nitrogen and silicon atoms, are
appealing ring structures in the development of silicon-containing functional molecules.
The development of general and efficient methods towards these motifs has therefore
attracted considerable attention from synthetic chemists. This short review intends
to highlight representative advances in the synthesis of five- and six-membered silaazacycles.
