Visible light induced hydrophosphinylation of unactivated alkenes catalyzed by salicylaldehyde

An air and water insensitive visible light induced hydrophosphinylation of unactivated alkenes is reported. A small amount of a simple and cheap compound, salicylaldehyde, is used as a photosensitizer. The reaction is carried out in a basic aqueous solution which enables the deprotonated salicylaldehyde to show visible light absorption.

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

Catalyst- and solvent-free hydrophosphination and multicomponent hydrothiophosphination of alkenes and alkynes

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 of diphenylphosphine to alkenes and alkynes, respectively, in the absence of a solvent and a catalyst. In the presence of elemental sulfur, the corresponding alkyl and alkenyl tertiary phosphine sulfides are synthesized in a three-component process. These simple methods, which meet most of the principles of Green Chemistry, are highly regioselective towards the anti-Markovnikov products and diastereoselective towards the Z alkenyl phosphines. The mechanistic aspects of the reactions are also tackled and the efficiency of the latter is compared with that of the catalytic methods.
