網頁2024年2月12日 · A modular and generic method for the Buchwald–Hartwig amination reactions of relatively unreactive aryl esters as acyl electrophiles and aryl chlorides as aryl electrophiles has been developed, leading to the efficient synthesis of amides/amines under air conditions and with low catalyst loadings. The succes 網頁The Buchwald group at MIT has developed a mild and high-yielding approach to arylated imidazoles using catalytic Cu (I) and a 1,10-phenanthroline ligand scaffold ( Scheme 4 ). 7 The reaction allows the use of either an aryl bromide or iodide as the electrophile and is tolerant to bulky substituents and various sensitive functional groups. Scheme 4. 網頁2024年8月15日 · Buchwald proposed general ligand design strategy shown below. They changed the functional groups to get a library of ligands, for different substrates. Different ligands will be discussed in detail in Scope part.
