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
Outer-Sphere Reactivity Shift of Secondary Phosphine Oxide-Based Nickel Complexes: From Ethylene Hydrophosphinylation to Oligomerization
A new dimension for secondary phosphine oxide (SPOs) ligands is described in this article. Demonstrated on original π-allylic nickel structures, these self-assembled complexes trigger catalytic hydrophosphinylation reactions. Addition of a Lewis acid B(C6F5)3 switches the reactivity towards migratory insertion and thus ethylene oligomerization through an unprecedented outer-sphere interaction with the coordinated SPO ligand. NMR experiments and X-ray analyses allowed for the observation of the formation of zwitterionic active species as well as their degradation pathway.

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

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.
