We present negative ion formation from collisions of neutral potassium atoms with neutral phenylboronic acid C 6 H 5 B(OH) 2 molecules in the lab frame energy range from 10 to 1000 eV. From the assignment of the negative ion time-of-flight (ToF) mass spectra, BO − is the main fragment detected at energies below 100 eV, however above 100 eV BO 2 − is the predominant fragment accounting on average for 30% of the total anion yield for collision energies above 250 eV. The rich fragmentation pattern results in the formation of more than thirty fragment anions, with twenty boron containing ions.
