A Cu(I)-photocatalyzed highly stereo- and regioselective synthesis of vinylphosphonates directly from alkyl aldehydes and alkynylphosphonates was successfully achieved.
An easily accessible Cu-β-CD complex has been introduced for C–P cross-coupling reactions of alkynes with both dialkylphosphites and phosphinoxides for the synthesis of alkynyl-phosphonates and -phosphinoxides.
Coinage (Au, Ag, Cu) metal-catalyzed (3 + 2) annulation of α-aminoketones and electron-deficient alkynes provides a modular one-step route to a variety of 3-EWG-substituted pyrroles.
Given that the EU has listed phosphorus as a critical raw material, the green aspects of phosphonate compounds, from synthesis, to applications, and recycling, are reviewed.
This study reports a method for benzylamine oxidative homocoupling to symmetric imines via copper catalysis using a substoichiometric dialkylphosphite additive, under ambient conditions, without requiring drying agents or other additives.
