Abstract

Mass spectra of four tetrahydrotetrabenzo[b,d,h,j] [1,6]diazacyclododecines are reported. Loss of phenan‐threne gives 2,2′‐diaminobiphenyl or the appropriate substituted diamine as the base peak in three cases. Substituents ortho to the biphenyl link substantially modify the fragmentation pattern. Mass spectra of the four 2,2′‐diaminobiphenyls have been determined for comparison.
