Selective N-monoalkylation of aromatic amines with 1° and 2° alcohols and conversion of aromatic amines to amides are performed immediately and in excellent yields using triphenylphosphine (PPh3) and 2,3-dichloro-5,6-dicyanobenzoquinone (DDQ) in dichloromethane at room temperature. Symmetrical and unsymmetrical N,N-dialkylation of aromatic amines are also carried out in modest yield at room temperature
立即使用三苯基膦(PPh 3)和2,3-二氯-5,6-二氰基苯并醌(DDQ)进行芳香族胺与1°和2°醇的选择性N-单烷基化以及芳香胺向酰胺的转化,收率很高。在室温下为二氯甲烷。通过该试剂体系,在室温下也以适度的产率进行芳族胺的对称和不对称的N,N-二烷基化。
