Abstract
The reaction between (bromodifluoromethyl)trimethylsilane (TMSCF2Br) and potassium thiocyanate providing TMSCF2NCS is described. The process involves the interaction of difluorocarbene with the nitrogen atom of the thiocyanate anion. The obtained silicon reagent served as a source of the fluorinated group and difluorocarbene in the reaction with N-alkyl imines, affording 2-(difluoromethylthio)-4-fluoroimidazoles.
期刊介绍:
Organic Letters invites original reports of fundamental research in all branches of the theory and practice of organic, physical organic, organometallic,medicinal, and bioorganic chemistry. Organic Letters provides rapid disclosure of the key elements of significant studies that are of interest to a large portion of the organic community. In selecting manuscripts for publication, the Editors place emphasis on the originality, quality and wide interest of the work. Authors should provide enough background information to place the new disclosure in context and to justify the rapid publication format. Back-to-back Letters will be considered. Full details should be reserved for an Article, which should appear in due course.
