Methyl Trideuteriomethyl (E)-(α-Bromoarylidene)malonates: Simple Stereochemical Probes in Nucleophilic Vinylic Substitution near the Retention/Stereoconvergence Borderline

Methyl trideuteriomethyl (E)-(α-bromo-p-methyl- and -p-nitrobenzylidene)malonates (4 and 5) were prepared.These electrophilic bromo olefins are activated to vinylic substitution by ywo chemically identical but isotopically distinguishable CO2Me groups.The

KINETICS OF THE REACTIONS OF A 2-BROMO-N-ETHYLPYRIDINIUM SALT WITH PRIMARY AROMATIC AMINES IN ACETONITRILE

The kinetics of the reactions of 2-bromo-N-ethylpyridinium bromide with ringsubstituted aromatic amines in acetonitrile at 25 deg C were investigated.The effect of the substituents in the benzene ring of the aromatic amines on the kinetics of nucleophilic substitution with the halogenopyridinium salt is described by a correlation equation with the ?0 constants.The reactivity of aliphatic and aromatic amines in reactions with 2-bromo-N-ethylpyridinium bromide in acetonitrile is described by a single correlation equation, which defines the joint contribution from electronic and steric factors of the substituets in the nucleophilic reagent.
