REACTIONS DES COMPOSES DU PHOSPHORE TRICOORDINE AVEC LES CETONES ET LES ESTERS ETHYLENIQUES: PROTOTROPIE, CYCLISATION, EXPANSION DE CYCLE

Article abstract of DOI:10.1016/S0040-4039(01)81914-6

Addition of trivalent phosphorus compounds with α,β-ethylenic ketones and esters leads to examples of prototropy or cyclisation or rearrangement with ring expansion from 5 to 7 atoms.
