Synthesis of vinylphosphine oxides: vinyl selenides as vinylating agents
摘要:
2-(Alkylselanyl)ethyl(diorgano)phosphine selenides readily accessible from secondary phosphine selenides and alkyl vinyl selenides react with aqueous solution of hydrogen peroxide to form vinylphosphine oxides in high yields.
Air-Induced anti-Markovnikov Addition of Secondary Phosphine Oxides and H-Phosphinates to Alkenes
摘要:
Air (oxygen) induces the addition of secondary phosphine oxides and H-phosphinates to alkenes to selectively produce the corresponding anti-Markovnikov adducts in good to high yields. Mechanistic studies show that the addition probably proceeds via a radical chain mechanism.
