Synthetic, Mechanistic and Photochemical Studies of Phosphate Esters of Substituted Benzoins

Synthesis of the phosphate esters of several benzoins, variously substituted with methoxy groups in one or both aromatic rings, proceeds via the corresponding cyclic ethylene ketals.These are phosphitylated with bis(2-cyanoethyl) diisopropylphosphoramidit

Vinylene 1,2-Bis(trifluoromethanesulfonates) from Azibenzils and Triflic Anhydride

Trifluoromethanesulfonic anhydride reacts with azibenzil and its 4-Cl and 4-OMe derivatives (2a-c) to give predominantly 1,2-diarylvinylene 1,2-bis(trifluoromethanesulfonates) (Z,E)-4a-c besides small amounts of the corresponding benzils 5a-c.The Z olefins are favored over their E isomers in all cases.The reaction begins with electrophilic attack on the oxygen of the diazo ketone by the anhydride; it represents a novel method of generating vinyl cations via vinyldiazonium ions.
