A Rh-catalyzed intermolecular coupling of diazomalonates with arene C-H bonds is reported. The reaction is initiated by electrophilic C-H activation, which is followed by coupling of the arylrhodium(III) complex with the diazomalonate. In most cases, arenes with oximes, carboxylic acids, and amines as directing groups cross-couple with diazomalonates with excellent regioselectivities and functional
报道了重氮丙二酸酯与芳烃 CH 键的 Rh 催化分子间偶联。该反应由亲电 CH 活化引发,随后是芳基铑 (III) 配合物与重氮丙二酸酯的偶联。在大多数情况下,以肟、羧酸和胺为导向基团的芳烃与具有优异区域选择性和官能团耐受性的重氮丙二酸酯交叉偶联,因此,该反应为特定应用的 α-芳基羰基化合物提供了一条新途径。
