Inner- and Outer-Sphere Roles of Ruthenium Phosphido Complexes in the Hydrophosphination of Alkenes

, 2015
An inner-sphere synthetic cycle for the hydrophosphination of alkenes is proposed, based on observed [2 + 2] cycloaddition of a wide range of alkenes at a coordinatively unsaturated RuPR2 complex.

Enantioselective organocatalytic hydrophosphination of ?,?-unsaturated aldehydes

, 2007
Optically active phosphine derivatives can be obtained in high yields and in up to 99?%?ee by using simple chiral amines to catalyze the hydrophosphination of ?,?-unsaturated aldehydes (see scheme, green sphere=chiral group).

A Highly Regioselective Palladium-Catalyzed Hydrophosphination of Alkynes Using a Diphosphine−Hydrosilane Binary System

, 2016
A novel transition-metal-catalyzed hydrophosphination of terminal alkynes using a diphosphine−hydrosilane binary system takes place regioselectively to provide vinylic phosphines, which undergo air oxidation during workup, affording the corresponding ...

Hydrophosphination of Bicyclo[1.1.0]butane-1-carbonitriles

, 2016
Hydrophosphination of bicyclo[1.1.0]­butyl nitriles with phosphine boranes and phosphites provided novel cyclobutyl-P derivatives. The reaction generally favors the syn-diastereomer, and the nitrile can be reduced and converted to other functional groups,

Intermolecular Zirconium-Catalyzed Hydrophosphination of Alkenes and Dienes with Primary Phosphines

, 2016
Catalytic hydrophosphination of terminal alkenes and dienes with primary phosphines (RPH2; R = Cy, Ph) under mild conditions has been demonstrated using a zirconium complex, [κ5-N,N,N,N,C-(Me3SiN­CH2CH2)2­NCH2CH2­NSiMe2­CH]Zr (1).

Insertion Reactions and Catalytic Hydrophosphination by Triamidoamine-Supported Zirconium Complexes

, 2016
Triamidoamine-supported zirconium phosphido complexes, (N3N)ZrPRR′ (N3N = N(CH2CH2NSiMe3)33−; R = alkyl, aryl; R′ = R, H), have been shown to catalyze the hydrophosphination of terminal alkynes as well as that of symmetric aryl and alkyl carbodiimides. A
