文摘

A novel preparation of cyclic chloro-3-phospholenium salts was described. The chloro-3-phospholenium salts were converted to borane complexes using LiBH4. A silane-free, one-pot preparation of 3-phosholene boranes was elaborated. Synthetic utility of isomerization of a chlorophospholenium salt was demonstrated. The mechanism was calculated for the isomerization of a chlorophospholenium salt.
