Abstract: We developed a synthetic methodology for preparing (E)-1,3,6-triarylfulvenes bearing three different aryl groups. The reaction of 1,4-diaryl-1-bromo-1,3-butadienes with silylacetylenes in the presence of a palladium catalyst produced (E)-3,6-diaryl-1-silyl-fulvenes in good to excellent yields. The (isopropoxy)silylated… read more here.

DOI: 10.1039/d2dt00892k
Abstract: The key problem of the instability of fluorine-containing diazadienes was addressed to perform the efficient synthesis of imidazolium salts containing fluorine substituents in the aryl groups. The subsequent reaction of fluorine-containing imidazolium compounds (NHCF) with… read more here.
