DFT studies clarify the roles of alkali metal cations and P-substituents in the H–P addition and formation and possible deactivation reactions of the catalytically active phosphinites in alkyne hydrophosphorylation promoted by M-HMDS precatalysts.
A visible-light-induced hydrophosphorylation of allenes with H-phosphine oxides is demonstrated to give a diverse range of alkenylphosphoryl compounds in a highly stereoselective and regioselective manner.
Metal-catalyzed highly Markovnikov-type selective hydrofunctionalization of terminal alkynes providing a straightforward and atom-economical route to access 1,1-disubstituted alkenes has been summarized.
In this report, we disclose a metal-free strategy for the regioselective hydrophosphorylation of alkynyl esters, providing a simple and green way to access P-containing olefins (E/Z up to >99%).
The diarylphosphinite complexes of the alkali metals exhibit a broad structural variety. Especially for potassium dimesitylphosphinite, the heterocubane cage can be broken down into dimeric K2O2 units by adding oligodentate ether molecules.
