New developments of proazaphosphatranes : from organocatalysis to halogen bonding

Abstract : In this dissertation, our goal is to explore new applications of proazaphosphatranes and their derivatives, especially in a confined space. In the first part, a comprehensive literature review regarding 1) discovery and application of proazaphosphatranes, 2) confined covalent cages based organo- and metal-catalysts, and 3) halogen bonding – an emergent noncovalent interaction has been demonstrated. Subsequently, proazaphosphatrane as highly efficient organocatalyst for the Strecker reaction is discussed. And a FLP (frustrated Lewis pair) system comprising an encaged proazaphosphatrane as Lewis base and TiCl4 as Lewis acid for MBH (Morita–Baylis–Hillman) reaction is reported. In the end, chlorinated azaphosphatrane is synthesized and studied in the recognition of different halide anions by halogen bonding, exhibiting a preferable affinity for chloride over bromide and iodide.
