General Synthesis of Unsymmetrical Tetrasubstituted Oxamides via 1,1′-(1,2-Dioxoethane-1,2-diyl)bis-1H-benzotriazole

All articles of this category Aliphatic, alicyclic, and aromatic secondary amines are converted by 1,1′-(1,2-dioxoethane-1,2-diyl)bis-1 H -benzotriazole, in a two-step process, into unsymmetrical tetrasubstituted oxamides in good yields. 1,1′-(1,2-Dioxoethane-1,2-diyl)bis-1 H -benzotriazole is available in high yield from benzotriazole and oxalyl chloride. unsymmetrical - tetrasubstituted - oxamides - benzotriazole
