Synthesis, characterization and cis–trans influence in cobaloximes with nioxime

Pyrazine bridged dicobaloximes with bis(thiophenyl)glyoxime and their molecular oxygen insertion

“…Upfield shift is maximum in the case of 3 because of strong CeH/p interaction (3.4 Å). 13 C chemical shift of pyrazine carbon further strengthen our hypothesis (see Table S4). As 13 almost similar as that of previously reported pyrazine complexes with dmgH and dpgH as equatorial ligand (Table S5).…”

Synthesis and Characterization of and Cis−Trans Influence in Cobaloximes with Glyoxime as the Equatorial Ligand

“…Most of the studies, however, have been confined to the trans effect only and have been carried out on cobaloximes with dmgH as the equatorial ligand. On the other hand, only a few studies on the 13 C NMR spectra of cobaloximes have been reported. 8b-d,f,g, Studies involving other oximes with varying steric and electronic properties such as gH, chgH, and dpgH have been few. Therefore, there is very little data available on the effect of the equatorial ligand field on the axial groups (cis influence). ,,12a,d,13b,14a,d,15a, …”

Weak interactions between furfuryl and equatorial dioxime ligand in furfuryl(O2)Co(dmgH)2Py: NMR, X-ray and DFT calculations

“…More than 1500 complexes and >150 crystal structures have been reported and in majority of the examples, dmgH has been used as the equatorial dioxime and the examples with other dioximes are rather few and many have been reported recently [6][7][8][9][10][11][12][13]. Most of the recent studies on cobaloximes have focused on the structure-property relationship [2,[13][14][15][16].…”
