DETAILS

Description (English)

Application
Reagent employed in a palladium-catalyzed enantioselective fluorination of t-butoxycarbonyl lactones and lactams.1 Also used in the electrophilic difluorination of dihalopyridines with butyl lithium2 and in the direct conversion of alcohols to dibenzenesulfonamides with triphenylphosphine.3
Stable, easy-to-handle, crystalline material which readily transfers F+ to enolates and carbanions.
Packaging
5, 500 g in poly bottle

Description (简体中文)

Application
用于叔丁氧基羰基内酯和内酰胺化合物的钯催化对映选择性氟化。1还可用于丁基锂作用下的二卤吡啶类化合物的亲电二氟化2，以及用于三苯基膦作用下的醇直接转化成双苯磺酰亚胺类化合物。3
稳定易处理的结晶物质，易于将 F+ 转化成烯醇化物和负碳离子。?
