12. Absolute concentrations are known from the amounts of reagents used to prepare the solutions. To the extent that the equilibrium expression for eq 2 is valid, however, the equilibrium constant depends on ratios of the species but is independent of their absolute concentrations.
13. 2Zn in benzene must also contain EtZnneo-Pe, but the difference in stability of an alkyl group in a symmetrical or mixed species is small (Mynott, R.; Gabor, B.; Lehmkuhl, H.; Döring, I. Angew. Chem., Int. Ed. Engl. 1985, 24, 335).
