Carbonylative formation of N-acetyl-2,6-difluorobenzamide through N–H bond activation of 2,6-difluorobenzamide with Ni(II) complex supported with phosphine ligands
摘要:
Fluorinated imide, N-acetyl-2,6-difluorobenzamide (C6H3F2-2,6)C(O)NHC(O) Me 2, could be obtained through one-pot reaction of NiMe2(PMe3)(3) with 2,6-difluorobenzamide (C6H3F2-2,6)C(O)NH2 1 in CO atmosphere. A postulated reaction mechanism via N-H bond cleavage and carbonylative reductive elimination on nickel center was partly experimentally confirmed. An important intermediate (C6H3F2-2,6)C(O)HNNiMe(PMe3)(2) 3 was isolated and structurally characterized. (C) 2011 Elsevier B. V. All rights reserved.
