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, RCoIII(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.
Co-C bond cleavage in the reactions of alkyl, benzyl and heteroaromaticmethyl cobaloximes with arene sulfenyl chloride: Homolytic and heterolytic pathways

The reactions of arene sulfenyl chlorides, ArSCl, (Ar=Ph, C6Cl5, 2,4 (NO2)2C6H3) with organocobaloximes, RCo(dmgH)2Py, (R=alkyl, benzyl and heteroaromaticmethyl) were carried out under thermal and photochemical conditions. A variety of organic and organometallic products are formed depending upon the substrate cobaloxime. For 3-methoxybenzyl and heteroaromaticmethyl cobaloximes the results suggest that they represent a unique class of cobaloximes whereby both the aromatic ring as well as the Co-C bond are highly activated towards attack by the arene sulfenyl chloride. Both homolytic as well as heterolytic pathways are operative.
