Electronic repulsions between a perepoxide intermediate and the allylic functionality in the product forming transition state, direct the regioselectivity in the photooxygenation of trisubstituted alkenes bearing an electron withdrawing group at β- position.
highly stereo- and regioselective hydrophosphorylation of terminalalkynes to E-alkenylphosphorus compounds was well developed. It represents a general and practical hydrophosphorylation method, of which diarylphosphine oxide, dialkylphosphine oxide and dialkyl phosphite all had effective P(O)H parts to react with different types of terminalalkynes. Contrary to previous air-sensitive reports, all the reactions

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.

Diphenylphosphine oxide and related P(O)H compounds react with propargyl alcohols at room temperature in the presence of a catalytic amount of Ni(O) complex and Ph2P(O)OH to produce high yields of phosphinoyl 1,3-dienes though an efficient in situ dehydration process.
