Abstract

The reaction of transition metal coordinated N, N-dialkylsubstituted N'-benzoyl thioureas with electrophilic agents differs from the reaction of the non-coordinated ligands. The nickel (II) chelates 1 form with organic acid chlorides RCOCI the N', N'-diacylated thioureas 2 and with thionyl chloride the n-(amino-thiocarbonyl) benzimide chlorides 3. The substitution of the chlorine in 3 yields new derivatives of thiourea: by the reaction of alcoholates N- ...
