Synthesis, Structure, and Reactivity of a Stabilized Phosphiranylimn Salt

摘要

Phosphiranes with a three-membered PC2 ring have unique electronic properties. Although their ring strain is smaller than that in cyclopropanes, they are highly reactive and display remarkable chemistry, such as [2+1] cycloreversions to olefins and phosphinidenes [R-P], cationic ring-opening polymerization to poly(ethylenephosphine), and special properties as ligands in transition-metal complexes for catalysis.
