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.

A new method for catalytic generation of a homoenolate equivalent and its application to carbon?carbon bond formation was developed by utilizing the [1,2]-phospha-Brook rearrangement under Br?nsted base catalysis. The α-oxygenated allyl anions, which can
Chiral ytterbium silylamide catalyzed enantioselective phospha-Michael addition of diethyl phosphite to chalcones

An efficient and enantioselective phospha-Michael addition of diethyl phosphite to chalcones has been established. In the presence of a catalytic amount of chiral lanthanide silylamide generated from [(Me3Si) 2N]3Yb(μ-Cl)Li(THF)3 and salen, the reaction produced the target γ-oxophosphonates with high yields and enantioselectivity.
