Electric Literature of 15679-12-6. Let’s face it, organic chemistry can seem difficult to learn. Especially from a beginner’s point of view. Like 15679-12-6, Name is 2-Ethyl-4-methylthiazole. In a document type is Article, introducing its new discovery.
We reported herein the Pd-catalyzed direct arylation of antipyrine using Pd(OAc)2 as catalyst associated with KOAc as inexpensive base. In most cases, diethyl carbonate was used a sustainable solvent. The reaction tolerated a wide range of functional groups on the aryl bromide partners (e.g., nitrile, nitro, chloro, fluoro, formyl, acetyl, propionyl, benzoyl, ester, methyl, methoxy). In addition, some nitrogen-containing heteroaryl bromides were also efficiently coupled with antipyrine. We also demonstrated that in contrast to 4-bromoantipyrine, 4-iodoantipyrine could be employed as an efficient heteroaryl source in Pd-catalyzed C?H bond arylation of 5-membered ring heteroarenes.
