(Difluoromethyl)trimethylsilane Chemical Properties,Uses,Production
Description
A direct nucleophilic difluoromethylation reagent. The nucleophilic activation of the silicon center with Lewis base initiators allows transfer of the difluoromethyl moiety to electrophiles such as aldehydes, ketones, and aldimines. The copper-mediated difluoromethylation of halides using TMSCF2H tolerates amine, ether, amide, ester, aromatic bromide, and protected alcohol functionalities in aryl iodides and occurs in high yield and stereoselectivity with vinyl iodides.
Uses
(Difluoromethyl)trimethylsilane, can be used for difluoromethylation of carbonyl compounds. Difluromethylated compounds are very useful in materials science and medicinal and agricultural chemistry.
Reactions
(1) Direct bromination to prepare TMSCF2Br.
(2) Difluoromethylation of aldehydes and ketones.
(3) Difluoromethylation of aldimines.
(4) Difluoromethylation of aryl and vinyl iodides.
