## Abstract The reaction of 3,4‐dihydroisoquinolinium salt 11 with phenyl‐N,N‐dimethylaminoacetylene 12 affords the (1:2)‐adduct, the dihydrobenzo(d)azecinium salt derivative 13. The structure assignment is based on a preliminary X‐ray analysis as well as on analytical and spectral data. It is assu
