Low-Temperature Template Synthesis of [4,6,6-Trimethyl-2,6-dithioxo-3,7-diazanon-4-enebis(imidothioato)] copper (II) in Gelatin-Immobilized Cu_2[Fe(CN)_6] Matrix Materials

摘要

Complexation in gelatin-immobilized copper (II) hexacyanoferrate (II) matrices on contact with alkaline (pH 10) aqueous solutions containing dithiooxamide and acetone was studied. Under these conditions, template synthesis occurs to give the chelate CuL[L is 4,6,6-trimethyl-2,6-dithioxo-3,7-diazanon-4-enebis-(imidothioato)ligand], with dithiooxamide and acetone acting as lignad synthons. The reaction pattern was suggested. Attempted reaction of dithiooxamide and acetone in solution in the absence of Cu(II) does not yield this ligand.
