Substituent effects on cyclobutyl and cyclopropylcarbinyl cations
Wiberg, Kenneth B.,Shobe, David,Nelson, Gordon L.
, p. 10645 - 10652 (2007/10/02)
The acetolyses of 3-substituted cyclobutyl tosylates (X = Ar, Cl, and OEt) were examined giving rate constants and product distributions. With the alkyl- and aryl-substituted compounds, the rate-determining step leads to the formation of a bridged cyclobu
