β-Deuterium Effects in Solvolytic Reaction of 1-Chloro-1-(4-phenoxyphenyl)ethane in Dipolar Aprotic Solvents
Preserved Fulltext
Kinetic deuterium effects in the solvolytic reaction of 1-chloro-1-(4-phenoxyphenyl)ethane in DMSO, acetonitrile, nitromethane, and DMF were found to be 1. 26-1. 37, which were larger than those in protic solvents. The difference may be attributed to the solvation of the transition state by protic solvents to reduce the electric charge of the carbonium ion intermediate.
