Synthetic Approaches for the Construction of Five- and Six-Membered Silaazacycles

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. 1 Introduction 2 Five-Membered Silaazacycles 2.1 Five-Membered Silaazacycles bearing a 1,2-N/Si Moiety 2.2 Five-Membered Silaazacycles bearing a 1,3-N/Si Moiety 3 Six-Membered Silaazacycles 3.1 Six-Membered Silaazacycles bearing a 1,2-N/Si Moiety 3.2 Six-Membered Silaazacycles bearing a 1,3-N/Si Moiety 3.3 Six-Membered Silaazacycles bearing a 1,4-N/Si Moiety 4 Conclusion
