## 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 fra
