GRAPHICAL ABSTRACT

ABSTRACT

The synthesis of novel functionalized 3H-1,2,3,4-triazaphosphole derivatives is presented, making use of the modular [3+2] dipolar cycloaddition reaction between an azide and a phosphaalkyne. These low-coordinate phosphorus heterocycles were prepared in high yield and could be characterized crystallographically. This strategy provides the possibility to access hitherto unknown chelating and potentially chiral P^O ligands based on triazaphospholes.
