Bh. Lipshutz et al., An electrospray ionization mass spectrometry study of the aggregation states of organocopper complexes in solution, ORGANOMETAL, 18(9), 1999, pp. 1571-1574
Using the technique of ESMS, a number of carbon-bound organocuprate species
derived from copper(I) halides and CuCN have been examined. The data obtai
ned indicate the presence of several anionic aggregates in solution.
