The nature of organocuprates of general formula R2Cu(CN)Li2, derived from CuCN and 2RLi, is described in terms of their structural integrity in solution.A combination of chemical and spectroscopic tests conclusively demonstrates facile dissociation-reassociation of alkyl groups on copper.Data derived from both IR and variable temperature NMR spectra suggest that different aggregation states between Et2O and THF based solutions of these reagents exist.
