资源简介：
A versatile, high-yielding synthesis of NHC-stabilized [PCl2]+ and [PCl]2+ phosphorus synthons has been achieved by using an “onio-substituent transfer” reagent. Subsequent functionalization yields access to cationic cyano- and azido-substituted derivatives which represent first examples of a displacement reaction on NHC-stabilized phosphorus(III)-centered cations. The new salts have been fully characterized by NMR spectroscopy and X-ray crystallography.
