Yb[bond]imine complex, [Yb(eta(2)-Ph(2)CNPh)(hmpa)(3)], to give alkenylphosphines and phosphine oxides after oxidative workup in good yields under mild conditions. This reaction is also applicable to various carbon[bond]carbon multiple bonds such as conjugated diynes and dienes, allenes, and styrene derivatives. Regio- and stereoselectivity and the scope and limitation of the present reaction clearly

An efficient olefinic C–P cross-coupling of alkenylsulfonium salts with secondary diarylphosphines is reported. The use of a palladacycleenables the facile formation of a C–P bond at the alkenyl moiety of alkenylsulfonium salts tolerating a wide range of functional groups under mildconditions. This protocol provides an easy access to various alkenylphosphine products in good to high yields with high

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 alkenylphosphine oxides, since it avoids the use of a metal catalyst that sometimes is difficult to remove from the products.

The hydrophosphination of carbon-carbon multiple bonds has been generally performed under acid, base or metal catalysis in different solvents. Herein, alkyl and alkenyl tertiary phosphines are obtained by the addition...
