Abstract

2-Fluorphenyllithium reacts with chloro-phenyl-phosphines Ph3-n PCl n , = 1, 2, 3 to give diphenyl-(2-fluorophenyl)phosphine 1. bis-(2-fluorophenyl)phenyl-phosphine 2 and tris-(2-fluorophenyl)phosphine 3. The new compounds and their oxides are characterized by 13C-, 31P-NMR and mass spectra. Reaction with bromine yields the dibromtriarylphosphoranes. These compounds form with o-aminophenols two permutation isomeric 2,2,2-triaryl-1,3,2Λ5-benzoxazaphospholes.

Die neuen Verbindungen und ihre Oxide werden durch die 13C-und 31P-NMR-sowie die Massenspektren charakterisiert. Umsetzung mit elementarem Brom liefert die Dibromtriarylphosphorane, die sich mit o-Aminophenolen zu den entsprechenden permutationsisomeren 2,2,2-Triaryl-1,3,2Λ5-benzoxazaphospholen umsetzen lassen.
