LDA-Mediated Synthesis of Triarylmethanes by Arylation of Diarylmethanes with Fluoroarenes at Room Temperature
摘要:
A practical and convenient approach for the secondary C(sp(3))-H arylation of diarylmethanes with various fluoroarenes is described. The reaction proceeds smoothly in the presence of LDA (lithium diisopropylamide) at room temperature and affords triarylmethanes in moderate to high yields.

日期:——
diarylketones leading to multiply arylated alkanes was developed. Diarylketones were reacted with diphenylphosphine oxide resulting in a phospha-Brook rearrangement, followed by palladium-catalyzed cross-couplings or a Friedel–Crafts type alkylation to afford the corresponding multiply arylated alkanes. A variety of diarylketones can be converted to multiply arylated alkanes such as diarylmethanes, tetraarylethanes

Mit Fluor enthaltenden Gruppen substituierte, symmetrische Benzophenone werden hergestellt, indem man mit Fluor enthaltenden Gruppen substituierte aromatische Verbindungen mit Formaldehyd und/oder einem Formaldehydderivat unter Zusatz von Fluorwasserstoff, Fluorsulfonsäure und/oder Schwefelsäure zu den entsprechenden Diphenylmethanen umsetzt und diese oxidiert. Die mit Fluor enthaltenden Gruppen substituierten, symmetrischen Benzophenone werden verwendet zur Herstellung von Polyetherketonen, indem man sie mit Diolen umsetzt. Neue, mit Fluor enthaltenden Gruppen substituierte, symmetrische Benzophenone werden auch beansprucht.
