Mechanistic Studies on the Palladium-Catalyzed Cross Dehydrogenative Coupling of P(O)-H Compounds with Terminal Alkynes: Stereochemistry and Reactive Intermediates

The mechanism of the palladium-catalyzed cross dehydrogenative coupling of P(O)-H compounds with terminal alkynes was studied. Successive ligand-exchange reactions of Pd(OAc)2 with a hydrogen phosphoryl compound and a terminal alkyne take place

Copper-Catalyzed Vicinal Cyano-, Thiocyano-, and Chlorophosphorylation of Alkynes: A Phosphinoyl Radical-Initiated Approach for Difunctionalized Alkenes

A copper-catalyzed difunctional cyano-, thiocyano-, and chlorophosphorylation reaction of alkynes with P(O)-H compounds and coupling partners (TBACN, TMSNCS, TMSCl) is described. The reaction introduces versatile groups (-P(O)R2 and -CN, -SCN, or -Cl) to form tri- and tetrasubstituted alkenyl phosphine oxides/phosphonates regio- and stereoselectively.

Additive-free coupling of bromoalkynes with secondary phosphine oxides to generate alkynylphosphine oxides in acetic anhydride

A coupling of bromoalkynes with secondary phosphine oxides was developed for the synthesis of alkynylphosphine oxides. This transformation was accomplished under additive-free conditions in acetic anhydride (Ac2O). The reaction could be carried out under mild conditions, and a wide range of secondary phosphine oxides were obtained in good yields.
