Dibisyl(fluorenylidene)stannene: evidence of its formation
摘要:
The dibisyl(fluorenylidene)stannene 4, obtained by dehydro-chlorination or -fluorination of the corresponding chloro- or fluoro-stannanes 5 and 6 by tert-butyllithium is an extremely air-sensitive compound. It has not been isolated, but identified by trapping reactions by lithio compound and water.
