Scheme 43 Cu Oac 2 Catalyzed Intramolecular C Sp 3 H Amidation For Download scientific diagram | scheme 43 cu(oac)2 catalyzed intramolecular c(sp 3 ) h amidation for β lactam formation from publication: copper‐mediated and catalyzed c‐h bond amination via. The first copper catalyzed intramolecular c(sp 3) h and c(sp 2) h oxidative amidation has been developed. using a cu(oac) 2 catalyst and an ag 2 co 3 oxidant in dichloroethane solvent, c(sp 3) h amidation proceeded at a terminal methyl group, as well as at the internal benzylic position of an alkyl chain. this reaction has a broad substrate.

Scheme 43 Cu Oac 2 Catalyzed Intramolecular C Sp 3 H Amidation For In 2007, fu and co workers [42] reported the copper catalyzed, tert butyl hydroperoxide (tbhp) assisted c–h amidation of tertiary amines 1. by heating at 80 °c, the c–h bond in dimethylaniline underwent direct amidation to provide products 3 in the presence of amides 2. on the other hand, the dephenylation transformation via c–c bond. The first copper catalyzed intramolecular c (sp (3)) h and c (sp (2)) h oxidative amidation has been developed. using a cu (oac)2 catalyst and an ag2co3 oxidant in dichloroethane solvent, c (sp (3)) h amidation proceeded at a terminal methyl group, as well as at the internal benzylic position of an alkyl c …. The first copper catalyzed intramolecular c (sp (3) ) h and c (sp (2) ) h oxidative amidation has been developed. using a cu (oac)2 catalyst and an ag2 co3 oxidant in dichloroethane solvent, c (sp. The c—h bond amination reaction is one of the most straightforward protocols in the c—n bond formation, showing "step" and "atomic" economy. as a catalyst for c—h amination reaction, copper exhibits its unique catalytic properties due to easily accessible oxidation states.
