QUESTION: Draw an arrow-pushing mechanism for the FIRST STEP of
this synthetic sequence.
In this laboratory experiment, you will synthesize a RTIL, 1-hexyl-3-methylimidazolium hexafluorophosphate, using a two-step process involving nucleophilic substitution and anion exchange. 1-Hexyl-3-methylimidazolium hexafluorophosphate and its structural analogs have long names. Therefore, they are often abbreviated as [Cn-mim X, where n = the number of carbons in the alkyl chain of the cation, ‘mim' stands for methylimidazolium and X = the anion. P -N N N-methylimidazole - NON...

13 SN1: Synthesis of tert-Butyl Chloride Alkyl halides can be prepared from their corresponding alcohols via an acid catalyzed substitution reaction. The mechanism of these acid catalyzed substitution reactions are labeled as SNI (substitution, nucleophilic, unimolecular) and S 2 (substitution, nucleophilic, bimolecular). Tertiary alcohols follow the Syl route, primary alcohols follow the Sy2 route, and secondary alcohols can follow either path. Under acidic conditions, the mechanism (Figure 1) of the Syl reaction involves rapid protonation of the alcohol, followed by...
