β-Ketophosphonates formation via deesterification or deamidation of cinnamyl/alkynyl carboxylates or amides with H-phosphonates

We report here an unprecedented Fe/Cu synergistically catalyzed deesterificative or deamidative oxyphosphorylation of unsaturated carboxylates or amides with H-phosphonates. The valuable β-ketophosphonates were obtained along with chemoselective cleavage of Csp2-C(CO) or Csp-C(CO) bonds in good yields under oxygen atmosphere with a wide substrate scope.

An efficient preparation of β-ketophosphine oxides from alkynylphosphine oxides with benzaldehyde oxime as a hydroxide source

An effective and facile transitio-metal-free method has been developed for the synthesis of β-ketophosphine oxides from alkynylphosphine oxides with benzaldehyde oxime as a hydroxide surrogate. The current methodology provides simple access to various β-ketophosphine oxides in moderate to excellent yields with a broad substrate scope.

Copper-Catalyzed Direct Oxyphosphorylation of Enamides with P(O)-H Compounds and Dioxygen

A simple and convenient copper-catalyzed direct oxyphosphorylation of enamides with P(O)-H compounds and dioxygen has been developed under mild conditions. This methodology can allow the synthesis of a series of valuable β-ketophosphine oxides/β-ketophosphonates in moderate to good yields with a broad substrate scope simply by using readily-available starting materials.

Cu(i)/Fe(III)-Catalyzed C-P cross-coupling of styrenes with H-phosphine oxides: A facile and selective synthesis of alkenylphosphine oxides and β-ketophosphonates

Cu(i)/Fe(iii)-Catalyzed phosphorylation and oxyphosphorylation of styrenes with H-phosphonates which can be controlled by varying the reaction temperature are developed. This study offers a new and expedient strategy for the synthesis of useful alkenylphosphine oxides and β-ketophosphonates in satisfactory yields. Moreover, the transformation is proposed to proceed via a radical process and exhibits a broad substrate scope and good functional group tolerance.
