Synthesis of supramolecular metallo-amine-oxy acid systems via crystal disassembly/reassembly

Abstract

Crystal disassembly and reassembly processes are exploited to develop more efficient routes to known compounds [CuI(phen)2)]I·H 2O (2) and [CuI(phen)2)] [(PhPO(OH)2) ·(PhP(O)2OH)] (3), and routes to novel compounds such as [CuI(phen)2)][(PhS(O)3)]·2H2O (4), a novel sulfonate analogue of (3). Previous attempts to produce (2) have involved 18 hour reflux of ethanolic solutions of [Cu(phen)I]. Here the same material was produced by oxidation of [Cu(I)(phen)2]I (1) with iodine for 20 min at 70 °C. Compound (3), which is generally prepared by oxidation of (1) with phenylphosphonic acid, was successfully obtained, and in significantly greater yield, by reaction of (2) with excess phenylphosphonic ..
