Comparative Study of Nucleophilic Addition to Free and Metal-Coordinated Carbocations
A kinetic study in acetone is prepared for phosphorus and nitrogen donor nucleophile addition to three carbocations: (p-(dimethylamino)triphenyl)methyl (1), pyronin (2), and (p-(dimethylamino)phenyl)tropylium (3).In the absence of steric effects, the Ritchie N+ correlation is obeyed by the reactions; i.e., relative nucleophilic reactivity is electrophile independent.More significantly, the relative reactivities of phosphorus and nitrogen donors toward free carbocations are the same as that observed for addition to metal-coordinated cyclic ?-hydrocarbons even though the latter reactions involve metal-carbon bond cleavage.Both types of reactions have similar transition states.
The reactant in an enzyme-catalyzed reaction is called a substrate. Enzyme inhibitors cause a decrease in the reaction rate of an enzyme-catalyzed reaction.I hope my blog about 1038-95-5 is helpful to your research., category: chiral-phosphine-ligands
