Details of Molecule benzaldehyde (in DMSO)
|Molecule class||Electrophiles » C-Electrophiles » Aldehydes|
E Parameter: -12.90
Only 1 reference nucleophile was used to determine the E parameter. Determined from the kinetics of an epoxidation reaction with a carbanion (ArSO2CHCl-) and corrected by the splitting ratio of forward and backward reaction.
The previously reported E = -19.5 holds for the gross rate constant of the reversible attack of the S-ylide (4-NC-C6H4)CH=SMe2 at PhCHO (JACS 2011, 133, 8240), in which the epoxide ring closure is rate-determining.
