    • We note that the fragmentation of the mononuclear complex, 4, HCu(4, which is formed on ESI of a methanolic solution of BINOL 4 and Cu(NO3)2 as the dominant ion, reveals subsequent losses of neutral BINOL 4 and OH radical. Thus, a complex of dehydrated BINOL 4 and Cu1 is formed as the final product, exactly as is observed in the reaction sequence, 2, H)2Cu2NO 3]+→, 4)Cu]+→[(4, H2O)Cu

    • Keto/enol rearrangements are generally assumed to be facile processes which are enabled by general acid/base catalysis in protic solvents. In the gas phase or aprotic solvents, however, 1,3-H transfers are anything but facile; see also: C. Trage, D. Schröder, H. Schwarz, Chem. Eur. J. 2005, 11, 619.
