Tetrazarsoles-A New Class of Binary Arsenic-Nitrogen Heterocycles

摘要

Triazadiphosphole was recently prepared from (Me3Si)2N- N(SiMe3)PCl2 and GaCl3 under mild conditions in a formal GaCl3-assisted [3+2] cycloaddition.The second example of a binary azaphosphole,the tetrazaphosphole,was formed in the reaction of Me3SiN3 with Mes*N=PCl (Mes*=2,4,6-tBu3C6H2),again catalyzed by GaCl3.
