Copper-catalyzed addition of H-phosphine oxides to alkynes forming alkenylphosphine oxides

We have developed efficient copper-catalyzed additions of P(O)H compounds to alkynes, and the reactions provided the regio- and stereoselective E-alkenylphosphine oxides under catalysis of the commercially available and inexpensive copper catalyst system

Regioselective Single and Double Hydrophosphination and Hydrophosphinylation of Unactivated Alkynes

A lanthanum-based N,N-dimethylbenzylamine complex was used as a precatalyst for both hydrophosphination and hydrophosphinylation of alkynes under mild conditions. In the case of hydrophosphination, the catalyst induced monoaddition with high regiospecific

Metal-Free Electrophilic Phosphination/Cyclization of Alkynes

A metal-free electrophilic phosphination reaction has been developed. Electrophilic phosphorus species generated in situ from secondary phosphine oxides and Tf2O smoothly couple with alkynes possessing pendant nucleophiles to afford the corresponding phosphinated cyclization products in good yield. Preliminary NMR studies show that phosphirenium species may be involved as intermediates of the cyclization reactions.

Copper (II)-catalyzed regio- and stereoselective addition of H/P(O)R 2 to alkynes

Cu(acac)2 is the new universal catalyst for β-E regio- and stereoselective syn-addition of the H-P(O)-bond of diphenylphosphine oxide, H-phosphinates, dialkylphosphites to various alkynes in the synthesis of P(O)-containing alkenes. Without additives and ligands Cu(II)-compounds showed better results than CuI or Ni(acac)2. The catalytic system developed is tolerant to typical organic functional groups present in the alkynes and to the nature of different substituents in the H-P(O)-compounds.

Regio- and stereospecific cleavage of stannyloxiranes with lithium diphenylphosphide

Unsubstituted or C-substituted stannyloxiranes reacted stereospecifically with lithium diphenylphosphide to give either β-hydroxyphosphane oxides resulting from α-opening or β-phosphanyl ketones by β-opening. Furthermore, the reactivities of distannyloxir

Regio- and stereospecific cleavage of silyl- and disilylepoxides with lithium diphenylphosphide

Unsubstituted or α- and β-C-substituted silylepoxides react stereospecifically with lithium diphenylphosphide, optionally followed by methylation, to give vinylphosphonium iodides or vinylphosphine oxides resulting from α-opening and silyl enol ethers, vi

Intermolecular hydrophosphination of alkynes and related carbon-carbon multiple bonds catalyzed by organoytterbiums

Intermolecular hydrophosphination of alkynes with diphenylphosphine is catalyzed by a Yb - imine complex, [Yb(η2-Ph 2CNPh)(hmpa)3], to give alkenylphosphines and phosphine oxides after oxidative workup in good yields under

Synthesis of lanthanide(II)-imine complexes and their use in carbon-carbon and carbon-nitrogen unsaturated bond transformation

Ytterbium and samarium metals reduced aromatic ketimines to give directly divalent azalanthanacyclopropane complexes 1 quantitatively, the structure of which was characterized by X-ray analysis. The imine complexes 1 catalyzed dehydrogenative silylation of terminal alkynes, hydrosilylation of imines and alkenes, and intermolecular hydrophosphination of alkynes. Moreover, dehydrogenative double silylation of conjugated dienes was achieved with 1.

Intermolecular hydrophosphination of alkynes and related carbon-carbon multiple bonds catalyzed by ytterbium-imine complexes

Catalytic intermolecular hydrophosphination of alkynes with Ph2PH has been achieved by using a ytterbium-imine complex, [Yb(η2-Ph2CNPh)(hmpa)6]. Thus, both terminal and internal alkynes were converted in high yi
