Deep cavitands provide organized solvation of reactions

Deep self-folding cavitands have been shown to stabilize the charged enolate intermediate of the α-deuteration of activated olefins by means of a network of organized solvation. Copyright

Synthesis and Chemistry of Donor/Acceptor-Substituted Cyclopropenes

Rhodium(II) acetate, or trifluoroacetate-catalyzed decomposition of 1-diazo-2-(trialkylsiloxy)propenes with electron-withdrawing groups at the 1-position results in the formation of highly reactive cyclopropenes.These cyclopropenes contain both donor and acceptor substituents on the alkene and are very susceptible to ring opening and fragmentation reactions.Nevertheless, when appropriately functionalized with bulky substituents they can be of sufficient stability to be isolated and characterized.

KINETICS AND MECHANISM OF THE INTERACTION OF AMINES WITH ARYL β-HALOETHYL SULPHONES

The influence of a number of factors, i.e. amine basicity, substrate structure, temperature and deuterium isotope effect, on the rate of phenyl β-bromoethyl sulphone and aryl β-chloroethyl sulphone 1,2-elimination by reaction with amines in acetonitrile was investigated.On the basis of a comparative analysis of the ρ0, β, kH/kD, ΔH(excit.) and ΔS25(excit.) values obtained with those for the reaction of β-halopropiophenone 1,2-elimination, the conclusion was drawn that the E2 mechanism with an anion-like transition state occurs for the given substrates under the conditions studied.
