Synthesis, structures and reactivity of N-donor-functionalised Cu(I) aryloxides

The preparation and characterisation of the Cu(I) aryloxides [Cu16(3-pyO)16(dppm)8] (1), [{Cu2(2-pyO)2(dppm)}2] (2) and [{Cu3(μ3-6-OQ)2(dppm)3}{(6-HOQ)2(μ-6-OQ)}] (3) (dppm = 1,2-bis-diphenylphosphinomethane, 6-HOQ = 6-hydroxyquinoline, py = pyridine) are described. A first attempt to employ organic anhydrides in insertion reactions with Cu(I) aryloxides was made producing the one-dimensional coordination polymer 1/∞[Cu3(3-pyO)(CO2C2H4Boc)(dppm−)(dppm)]∞ (4) (Boc = tert-butoxycarbonyl).

The acid–base reactions of arylhydroxides and [CuOtBu] provide a new route to oligomeric Cu(I) aryloxides with remarkable solid-state structures. A first attempt to employ the compounds in insertion reactions with organic anhydrides was made and shows that Cu(I) aryloxides might represent useful building blocks for metallo-organic open frameworks.Figure optionsDownload as PowerPoint slide
