Formation of a Silafluorene from an Intramolecular Ring-Closure Reaction

Formation of a Silafluorene from an Intramolecular Ring-Closure Reaction

Trichloro- and trifluoro-2,4,6-triphenylphenylsilanes, 3a and 3b, yield the highly crystalline 1,3-diphenyl-9,9-bis(trimethylsilyl)-9-silafluorene, 7, when treated with lithium metal and chlorotrimethylsilane in THF. The X-ray structure of the silafluorene is reported along with 1H, 13C, and 29Si NM...

Zusammenfassung:Trichloro- and trifluoro-2,4,6-triphenylphenylsilanes, 3a and 3b, yield the highly crystalline 1,3-diphenyl-9,9-bis(trimethylsilyl)-9-silafluorene, 7, when treated with lithium metal and chlorotrimethylsilane in THF. The X-ray structure of the silafluorene is reported along with 1H, 13C, and 29Si NMR data.
