Abstract
Reaction of 2-BrC6H4PCl2 (1) with methyl lithium gave 2-BrC6H4PMe; (2). Metalation of 2 with n-butyl lithium and further reaction of the lithio-derivative 2-LiC6H4PMe2 with triphenyl phosphite yielded the title compound. P(C6H4PMe2-2)3 (3). characterized by NMR and mass spectroscopy as well as by an X-ray structure analysis. Quaternization of 2 with methyl iodide gave [2-BrC6H4PMe3]I (2a). the molecular structure of which has also been determined by singlecrystal diffraction methods.Keywords
