Аннотация

Intramolecular cyclization of bromides of diethyl-, dipropyl-, and penthamethylenepropargyl[3-(4-bromophenyl)prop-2-ynyl]ammonium into 6-bromobenzo[f]isoindolinium bromides catalyzed with bases occurs with moderate self-heating. The morpholine analog even in more diluted solutions reacts with vigorous self-heating. Cyclization of dimethyl analog takes place only at heating at 80–85°C during 1 h.
