C-H arylations of weakly coordinating benzoic acids were achieved by versatile ruthenium(ii) catalysis with ample substrate scope. Thus, user-friendly ruthenium(ii) biscarboxylate complexes modified with tricyclohexylphosphine enabled C-H functionalizations with aryl electrophiles. The unique versatility of the ruthenium(ii) catalysis manifold was reflected by facilitating effective C-H activations with aryl, alkenyl and alkynyl halides.
通过通用的钌(II)催化实现了弱配位苯甲酸的C-H芳基化,底物范围广泛。因此,用三环己基膦修饰的用户友好型钌(II)二羧酸酯配合物能够与芳基亲电试剂进行C-H官能化反应。钌(II)催化体系的独特通用性体现在能够促进与芳基、烯基和炔基卤化物的有效C-H活化反应。
