Rhodium-catalyzed anti-markovnikov-type hydrophosphination of terminal alkynes with diphosphines and hydrosilanes in the presence of oxygen

A novel rhodium(I)-catalyzed hydrophosphination of terminal alkynes with diphosphines and hydrosilanes takes place regioselectively in the presence of small amounts of oxygen. After air-oxidation during workups, the corresponding anti-Markovnikov-type vinylic phosphine oxides were obtained in good yields. Copyright Taylor & Francis Group.

MANUFACTURING METHOD OF ALKENYL PHOSPHORUS COMPOUND

PROBLEM TO BE SOLVED: To provide a general synthesis method capable of providing various alkenyl phosphorus compound and a derivative thereof using a raw material which is easily available and easily handled without using a catalyst. SOLUTION: An alkenyl

Radical Hydrophosphorylation of Alkynes with R2P(O)H Generating Alkenylphosphine Oxides: Scope and Limitations

Radical hydrophosphorylation of aliphatic terminal alkynes with H-phosphine oxides can produce the corresponding anti-Markovnikov alkenylphosphorus adducts in moderate yields. This method is a cleaner approach for the preparation of the corresponding alke

Catalytic Asymmetric Synthesis of Phosphine Boronates

The first catalytic enantioselective synthesis of ambiphilic phosphine boronate esters is presented. The asymmetric boration of α,β-unsaturated phosphine oxides catalyzed by a copper bisphosphine complex affords optically active organoboronate esters that bear a vicinal phosphine oxide group in good yields and high enantiomeric excess. The synthetic utility of the products is demonstrated through stereospecific transformations into multifunctional optically active compounds. Ambiphilic phosphine boronate esters are obtained by the asymmetric boration of α,β-unsaturated phosphine oxides with a copper/bisphosphine catalyst in good yields and high enantioselectivity. The synthetic utility of the products is demonstrated through stereospecific transformations into multifunctional optically active compounds.

Selective addition of P(O)H bonds to alkynes catalyzed by transition metals immobilized on polystyrene-bound triphenylphosphine

Addition of P(O)H bonds to alkynes catalyzed by transition metals (Rh, Pd, and Ni) immobilized on polystyrene-bound triphenylphosphine proceeded efficiently to afford high yields of the addition products with high regioselectivity. The immobilized catalys

Highly regio- and stereoselective hydrophosphinylation of acetylenes with diphenylphosphine oxide catalyzed by immobilization of rhodium in MCM-41

Highly regio- and stereoselective hydrophosphinylation of a wide range of acetylenes with diphenylphosphine oxide was achieved in toluene at 70 °C in the presence of 2 mol% of an MCM-41-immobilized bidentate phosphine rhodium complex [MCM-41-2P-RhCl(PPhs
