Primary alkyl halides do not undergo elimination reactions. o. SN2 reactions of secondary alkyl bromides with NaCN proceed faster in methanol than in DMSO.
DMSO has been used as an industrial solvent since the mid-1800s. From about the mid-20th century, researchers have explored its use as an anti-inflammatory agent.
In SN2 reactions, primary and secondary alkyl halides and sulfonates are readily displaced by N3- , resulting in alkyl azides: The usual procedure is to use an azide salt such as NaN3 or KN3 with the.
