In general, a Lewis acid-base reaction is represented by the scheme A + :B → A―B. Such reactions occur widely in chemistry, but the singular characteristic of metal ions is that they can act as acceptors to several ligands. The actual number of ligands that attach to a metal ion is...
10). Some o-quinones undergo 1,4-Michael reaction with the parent catechols to gives rise to dimeric products with a dibenzodioxin skeleton. An example was seen in the tyrosinase-catalyzed oxidation of hydroxytyrosol [(2-(3,4-dihydroxyphenylethanol)) [64] (Figure 14). However, this type ...
The concentration of the reaction product was used as a performance indicator to evaluate the MSFO algorithm in dealing with dynamic optimization problems in chemical processes.
