Unimolecular Solvolyses in Ionic Liquid: Alcohol Dual Solvent Systems
Molecules, 2016 A study was undertaken of the solvolysis of pivaloyl triflate in a variety of ionic liquid:alcohol solvent mixtures. The solvolysis is a kΔ process (i.e., a process in which ionization occurs with rearrangement), and the resulting rearranged carbocation ...

Nucleophile-Assisted Alkene Activation: Olefins Alone Are Often Incompetent
, 2016 Emerging work on organocatalytic enantioselective halocyclizations naturally draws on conditions where both new bonds must be formed under delicate control, the reaction regime where the concerted nature of the AdE3 mechanism is of greatest importance ...

Nucleophilicity scale for n- and π-nucleophiles
Chemical Physics Letters, 2006 Abstract A recently introduced empirical nucleophilicity index for a series of n- and π-nucleophiles was evaluated. The index is based on the frontier molecular orbital information of the nucleophile and its electrophilic partner. The model is validated against kinetic data of alkenes, phosphanes, phosphites and amines interacting with the ...

Regioselective ring opening of aziridine for synthesizing azaheterocycle
Frontiers in Chemistry, 2023 Aziridine had different regioselective ring openings depending on the functional group of its alkyl substituent. In the case of the alkyl group bearing γ-ketone at the C2 substituent of aziridine, the ring opening by the hydroxy nucleophile from H2O ...
