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