A laser desorption ionization mass spectrometry investigation of triarylboranes and tri-9-anthrylborane photolysis products

Laser desorption ionization (LDI) mass spectrometry of tri-9-anthrylborane (Anth3B) photolysis products confirm 9,9′-dianthryl as the major product and are consistent with anthrylborylene formation. LDI mass spectra of several arylboranes yield ions in good yield and for Anth3B, evidence of AnthB: intervention.
