Electrochemical Dehydrogenative Coupling of Alcohols with Hydrogen Phosphoryl Compounds: A Green Protocol for P?O Bond Formation
This study reports the environment-friendly electrochemical transformation of structurally diverse phosphorus compounds and alcohol into phosphonates in the presence of ammonium iodide as electrolyte and redox catalyst in acetonitrile at ambient temperature. This method for P?O bond formation exhibits remarkable features, such as transition metal- and oxidant-free conditions. A reliable mechanism is proposed after control and cyclic voltammetry experiments. (Figure presented.).
Evaluation of Phosphinic Acid Derivatives as Reagents For Amine Protection in Peptide Synthesis
The results of a kinetic study of the acid-catalysed methanolysis of a series of N-(2-phenyl-ethyl)phosphinamides incorporating selected substituents on phosphorus have been evaluated in order to define the optimum reagent and conditions for amine protection of α-amino acids during peptide synthesis.
