    Description / Table of Contents: Abstract The attempted preparation of 4-vinyltriarylmethyl radicals by interaction of 4-vinyltriarylmethylchlorides with metals yielded unstable radical intermediates immediately undergoing further reaction to give polymers of a quinodimethane structuretype. 1,4-α,α-Diphenylquinodimethane, obtained from 4-methyltriphenylmethyl chloride and pyridine in solution, was used as a model compound. It cannot be isolated and readily polymerizes to give poly-1,4-α,α-diphenylxylylene identified by IR and NMR spectra.
    Notes: Zusammenfassung Beim Versuch zur Darstellung von 4-Vinyltriarylmethylradikalen durch Umsetzung von 4-Vinyltriarylmethylchloriden mit Metallen entstehen intermediär Radikale, die jedoch sofort in einer mesomeren Form weiterreagieren, wobei Polymere mit Chinodimethan-Strukturen entstehen. Als Modell hierfür dient das gelbe 1,4-α,α-Diphenylchinodimethan, das aus 4-Methyltriphenylmethylchlorid und Pyridin in Lösung erhalten werden kann; es ist nicht in fester Form isolierbar und polymerisiert sich leicht zu Poly-1,4-α,α-diphenylxylylen, das durch IR- und NMR-Spektren identifiziert wird.
