Synthesis and Characterization of Protonated Alkylcobaloximes and Related Compounds

Published

Journal Article

Five alkylaquocobaloximes1 have been protonated in aqueous solution to yield a series of crystalline compounds of the general formula [Co(dmgH)(dmgH)(R)(Cl)]H2O where R- = CH3-, C2H5-, n-C3H7-, l-C3H7-, or C6H11-. Protonation can also be achieved under strictly anhydrous conditions to give the compound Co(dmgH) (dmgFH2) (CH3) (Cl). These new compounds are compared with the previously known cobaloximes of the general formula Co(dmgH)(dmgH2)(X)(Y) where X- = Y- = CL, X- = Y- = SCN-, X- = Y- = CN-, or X- = SCN- and Y- = CN-. Based primarily on infrared spectroscopy, it is concluded that protonation occurs at a hydrogen-bridged oxime oxygen of the dimethylglyoxime ligand system for all the cobaloximes studied. © 1975, American Chemical Society.
