Pallado-catalysed hydrophosphination of alkynes: access to enantio-enriched P-stereogenic vinyl phosphine–boranes

P(iii)-cyclic oligomers via catalytic hydrophosphination

A bulky secondary phosphine with an alkynyl substituent was prepared and shown to undergo catalytic hydrophosphination to give cyclic oligomers.

Synthesis of New Enantiomerically Enriched β-Hydroxy-γ-amino Phosphines by Selective Transformation of Naturally Occurring Amino Acids

Ring opening of amino epoxides derived from naturally occurring amino acids with lithium diphenylphosphido borane is reported as an efficient approach to a new family of enantiomerically enriched multifunctional phosphines.

A novel approach to phosphonic acids from hypophosphorous acid

A novel access to phosphonic acids via Pd-catalyzed tandem carbon-phosphorus bond formation - oxidation processes was developed. The procedures involve atom-economical and environmentally friendly functionalization reactions of hypophosphorous acid (H(3)PO(2)) and H-phosphinic acids [RP(O)(OH)(H)].

Organocatalytic asymmetric hydrophosphination of nitroalkenes

The use of a bifunctional Cinchona alkaloid catalyst has provided a new organocatalytic strategy for the enantioselective addition of diphenylphosphine to a range of nitroalkenes, affording optically active beta-nitrophosphines (up to 99% ee after crystallization); this organocatalytic approach, providing a direct route to a new class of potentially useful enantiopure P,N-ligands, constitutes a bridge between the two complementary areas of asymmetric catalysis: organo- and metal-catalyzed transformations.
