Abstract

Syntheses and spectroscopic features (IR, NMR and ESI MS) are reported for five 1:2 adducts of CuX with dppe (X = I, ClO4, NCS, O3SCF3 (equivalent to tfs) BH4; dppe = Ph2P(CH2)(2)PPh2). ESI MS and P-31 NMR spectroscopy indicate that these species dissociate in solution yielding free diphosphine and 3:2 species. A single crystal X-ray structure determination has been carried out on Cu(dppe)(2)NCS defining a four-coordinate complex of the form [(P,P'-dpex)M(P-dpex)X] for M = Cu, the thiocyanate being N-bound; the ionic [Cu(P,P'-dppe)(2)]tfs has also been structurally characterized.
