Reactivity studies of aryl cobaloximes with molecular oxygen and electrophiles

Isonicotinate-Zn(ii)/Cd(ii) bridged dicobaloximes: synthesis, characterization and electrocatalytic proton reduction studies

“…pseudo-octahedral cobalt complexes of glyoximato equatorial ligands and two trans-axial ligands have been extensively studied and showed hydrogen evolution at relatively lower overpotential. [13][14][15][16][17][18][19][20] Initially, cobaloximes were synthesized and studied to mimic the Vitamin B 12 chemistry, [21][22][23][24][25][26][27][28][29][30][31][32][33][34] but due to their rich coordination chemistry, these have been utilized in many catalytic reactions as well as in organic synthesis. [35][36][37][38][39][40][41][42][43][44][45][46][47][48][49][50] In the present time, cobaloxime complexes have been identified as one of the most active series of molecular catalysts for electrocatalytic and photocatalytic hydrogen production because of their low cost, easy synthesis and tuning of catalytic properties by changing the substituents in the equatorial and/or axial ligands.…”
