Abstract

C-8-substituted N-methyl-1,2,3,4-tetrahydroisoquinoline radical cations lose the complete substituent in a one step reaction giving rise to an unexpected ion at m/z 146, which is probably identical with the dihydroisoindolylmethyl- cation A. The dihydroisoindoles 1, 10, and 16 were prepared as potentially alternative precursors of ion A. However, the ion at m/z 146 in their EI mass spectra is of ...
