5-Substituted heteroaromaticmethyl cobaloximes are synthesized by a very simple reaction of arenesulfenyl chloride, ArSCI (Ar = Ph, C₆Cl₅ and 2,4-(NO₂)₂C₆H₃) with heteroaromaticmethyl cobaloximes, RCo^III(dmgH)₂Py [R = 2-and 3-thienylmethyl, furfuryl] in the dark at 0°C. As organocobaloximes are susceptible to Co-C bond cleavage by the electrophiles and free radicals, the ring substitution is quite remarkable.
