A facile hydrophosphonylation of alkenes by phosphites promoted by potassium carbonate was developed. The reaction features include easy handling, environmental friendliness, and avoidance of the use of strong bases. A variety of alkenes are tolerated in this reaction, with moderate to excellent yields.

Herein we report the synthesis of three heteroleptic first-row transition metal(II) complexes containing carbazolido NNN pincer ligands and conversion to the corresponding metal(I)-carbonyl complexes via a reductive carbonylation route. These complexes are precatalysts for the hydrophosphination of activated alkenes, affording a cobalt-catalysed hydrophosphination process that solely and selectively yields the β addition (anti-Markovnikov) product. The scope of this transformation has been investigated using a variety of activated alkenes. Isolation and characterisation of substrate-coordinated intermediates reveal available coordination sites, which provide insight into the proposed catalytic cycle. (Figure presented.).

The PBu3-catalyzed conjugate addition of diphenylphosphine oxide to unsubstituted and substituted electron-deficient alkenes is reported. β-Substituted α,β-unsaturated esters, trans-methyl crotonate and trans-methyl cinnamate, known for their r
Me3P-catalyzed addition of hydrogen phosphoryl compounds P(O)H to electron-deficient alkenes: 1 to 1 vs 1 to 2 adducts

Trimethyl phosphine was used as an efficient catalyst for the addition of P(O)-H compounds to electron-deficient alkenes. The addition reactions were generally conducted using a catalytic amount of Me3P under mild reaction conditions. Both 1 to 1 and 1 to 2 adducts were obtained.

The title compounds may be made by addition of phosphorus nucleophiles (Ph2PO-, Ph2POMgX, Ph2PCl) to enones, by addition of phosphorus-stabilised carbanions to a α-carbonyl cation equivalents (2,3-dichloropropene, epoxides, and α-MeO-ketones) and by oxidation of allyl diphenylphosphine oxides.
