Able to perform backside attack in SN2 reaction. Is it a strong base? If there is no protic solvent, will attack Beta-carbon-hydrogens to form carbocations in E2 reaction. Step 4: The Substrate Is the alpha carbon Primary (1o)? Can only go through an SN2 reactio...
A distinct geometrical preference is associated with the change in mechanism: in a tight SN2 transition state the nitrogen lone pair is turned to avoid repulsive interaction, while it parallels the reaction coordinate in a loose, SN1-like transition state....
Sn1 & Sn2 reaction with 1-Bromobicyclo[1.2.2]heptane « on: June 24, 2010, 12:27:46 AM » What is unique about this alkyl halide (1-Bromobicyclo[1.2.2]heptane) that prohibits a reaction of both Sn1 & Sn2? I know that Sn2 will not occur due to the Br being attached to ...

SN2 mechanismsbenzyl tosylatesYukawa–Tsuno equationThe rate data for the Menschutkin reaction between strongly activated Z-substituted benzyl p-toluenesulfonates and Y-substituted N,N-dimethylanilines in acetonitrile at 35 °C fit the equation, kobs = k1 + k2 [DMA], which is...
1-Arylethyl bromides react with pyridine in acetonitrile by unimolecular and bimolecular processes. These processes are quite distinct and this fact affords clear evidence for the duality of clean SN1 and SN2 mechanisms, occurrence of independent SN1 and SN2 reaction processes without an intermediate...
