✦ Synopsis

We report here the electron impact (EI) mass spectra of eight 3-phenyi-2,l -benzisoxazoles (l), seven of which bear substituents in the benzo ring at positions 5 or 6. H 1 (Ph=C,H,) 2 a These two ions, C,, H, and CloH,N, could not be resolved from one another or from '2C,0'3C,H7. The experimental mass measurement corresponded to Cl0H,N. The B/E linked scan (see Fig. 2) indicates that M+' loses 55 mass units. This mass loss fits either or both of M -(CO + HCN) and M -(CO + H + C,H,).
