| | Fluoromethyl phenyl sulfone Usage And Synthesis |
| Description | Fluoromethyl phenyl sulfone is a useful nucleophilic monofluoromethylation reagent for the
synthesis of fluoromethyl alcohols and amines. In the nucleophilic reaction step, strong bases such
as LiHMDS and n-BuLi are used to generate the nucleophilic (phenylsulfonyl)fluoromethyl anion.
In the desulfonylation step, sodium/mercury amalgam and magnesium are the commonly used
reductive reagents. Besides, the addition reaction between fluoromethyl phenyl sulfone and
carbonyls can be used to prepare monofluoroaklenes via acylation–elimination. | | Uses | Fluoromethyl phenyl sulfone can be used to prepare monofluoroaklenes and chiral α-Monofluoromethyl Amines. Highly stereoselective nucleophilic monofluoromethylation of (R)-(tert-butanesulfinyl)imines with fluoromethyl phenyl sulfone was achieved to afford α-monofluoromethylamines with a nonchelation-controlled stereoselectivity mode. By using the same chemistry, (R)-(tert-butanesulfinyl)imines bearing a terminal tosylate (OTs) group can be converted to α-monofluoromethylated cyclic secondary amines with high stereoselectivity. | | Reactions | (1) Monofluoromethylation of aldehydes and ketones.
(2) Monofluoromethylation of aldimines and ketimines.
(3) Monofluoromethylenation of aldehydes and ketones.
(4) (Phenylsulfonyl)fluoromethylation of esters.
