A palladium catalyzed carbonylative cross-coupling of difluoroalkyl halides with alkyl-9-BBN under 1 atm of CO has been developed. The reaction shows broad substrate scope and high functional group tolerance, even toward complex pharmaceuticals, providing a general and straightforward method to access alkyldifluoroalkyl ketones. Preliminary mechanistic studies reveal that a radical pathway is involved
已开发出钯催化的二氟烷基卤化物与烷基-9-BBN 在 1 个大气压的 CO 下的羰基化交叉偶联。该反应显示出广泛的底物范围和高官能团耐受性,甚至对复杂的药物也是如此,为获取烷基二氟烷基酮提供了一种通用且直接的方法。初步的机理研究表明,该反应涉及自由基途径。
