摘要：

Fluorenyl substituted m-xylylene tripler diradicals are conveniently generated from the corresponding dichloride precursors upon pbotolysis at <100 K in 2-MeTHF glass. Under similar conditions tert-butyl substituted Schlenk type m-xylylene could not be generated from the dichloride precursor 6. Compound 6, however could be dehalogenated with zinc dust in both toluene and 2-MeTHF to produce the tripler diradical. (C) 1997 Elsevier Science Ltd. All rights reserved.
