Efficient iron-catalyzed N-arylation of aryl halides with amines.
A practical and promising protocol was developed for N-arylations of various amines with differently substituted aryl halides. The processes are efficiently promoted by the catalyst system involving the environmentally benign Fe2O3 and the universal ligand L-proline. The versatility, convenient operation, low cost, and environmental friendliness, in combination with the high yields, render this...
متن کاملMechanistic studies on the copper-catalyzed N-arylation of amides.
The copper-catalyzed N-arylation of amides, i.e., the Goldberg reaction, is an efficient method for the construction of products relevant to both industry and academic settings. Herein, we present mechanistic details concerning the catalytic and stoichiometric N-arylation of amides. In the context of the catalytic reaction, our findings reveal the importance of chelating diamine ligands in cont...
متن کاملCopper-catalyzed sequential N-arylation of C-amino-NH-azoles.
Copper(II)-catalyzed boronic acid promoted C-N bond cross-coupling reactions have been successfully developed for sequential N-arylation of C-amino-NH-azoles. These general protocols are compatible with a variety of aryl/hetero-aryl boronic acids and provided rapid access to a diverse array of diarylaminoazole derivatives in a two-step sequence or in one-pot.
متن کاملN-Arylation of amines, amides, imides and sulfonamides with arylboroxines catalyzed by simple copper salt/EtOH system
The coupling of arylboroxines with a variety of amines, amides, imides and sulfonamides catalyzed by a copper salt/EtOH system has been developed. In the absence of a base or additive the corresponding N-arylation products were obtained in moderate to excellent yields.
متن کاملCopper-TBAF catalyzed arylation of amines and amides with aryl trimethoxysilane.
A copper-catalyzed C-N bond forming reaction among aryl siloxane and primary, secondary amines as well as amides has been described. The reaction was conducted in the presence of P(C6F5)3 and 4 A molecular sieves in CH2Cl2 at room temperature under O2. A catalytic amount of TBAF was employed to activate aryl siloxanes.
