Cp∗Co(III)-catalyzed ortho C H amidation of 2-pyridinyl ferrocenes with 1,4,2-dioxazol-5-ones
摘要:
ortho-Amidation of 2-pyridinyl ferrocenes with 1,4,2-dioxazol-5-ones was achieved via Cp*Co(III)-catalyzed direct C-H bond functionalization reaction. In the presence of Cp*Co(CO)I-2, in combination with AgPF6 and AgOPiv, a wide range of ferrocene-based amidated products were obtained in up to 96% yield under mild reaction conditions. A gram-scale reaction proceeded smoothly with high efficiency. Isoquinoline and pyrimidine are also suitable directing groups in this transformation. (C) 2018 Elsevier Inc. All rights reserved.

preparation of a series of complexes of the types [RhCl(CO)2(L)], [RhCl(cod)(L)] and [Rh(cod)(L)2]ClO4, where L is a ligand incorporating a ferrocenyl group and a pyridine ring is described. Complexes were characterized using NMR, IR and electronic spectroscopy. The electrochemical behaviour of the complexes was examined using cyclic voltammetry. The X-ray structures of three of the complexes, [RhCl(CO)2NC5

1'-dipyridylferrocene with [PtCl2(DMSO)(2)] yields the doubly cyclometalated complex sigma-Pt2Cl2(DMSO)(2)[Fe[eta(5)(C5H3(2-C5H4N)(2)](2)]} as a mixture of meso-and d, l-diastereomers. An X-ray structure determination of the obtained triclinic crystals (space group P (1) over bar) shows, however, only the chiral d,l form as a racemic mixture.

Coordination studies of the substituted pyridines (L) were carried out with platinum, palladium, rhodium and iridium. This resulted in the preparation of the following types of complexes: [MCl(CO)2(L)] and [M(cod)(L)2]ClO4 where M=Rh or Ir, cod=1,5-cyclooctadiene; [M′Cl2(L)2] where M′=Pt or Pd. The X-ray crystalstructure of trans-dichlorobis(3-ferrocenylpyridine)palladium was obtained. The complexes were screened

Amidation of N-containing heteroaryl ferrocenes with 1,4,2-dioxazol-5-ones as the amidated reagents was achieved via a Rh-catalyzed direct C-H functionalization reaction. Under mild reaction conditions, a wide range of N-ferrocenyl amides were obtained-in up to 99% yield. Transformations of the amide group were also feasible.
