Mass spectrometric studies. III. Bis(diphenylamino)methane, Bis(diphenylphosphino)methane, Bis(diphenylarsino)methane, and related compounds

Abstract

The compounds listed in the title, together with the analogous 1,2-bis(diphenyl-phosphino)- and 1,2-bis(diphenylarsino)-ethanes, as well as triphenylarsine have been subjected to electron bombardment at 70 eV. The nitrogen compound undergoes simple fragmentation whereas the diphosphines and the diarsines undergo fragmentations which clearly demonstrate migration of phenyl groups to give, inter alia, triphenylphosphine and triphenylarsine cations. These subsequently fragment in the same way as intact triphenylphosphine and triphenylarsine molecules.
