Methylene bridged polycyclic diazocines 2a and 2b were obtained in reactions of 1,3-indanedione, or benzo[b]thiophen-3(2H)one-1,1-dioxide, or 2,2′-methylene derivatives 3a,b with paraformaldehyde and ammonia or hexamethylenetetramine in acidic medium. A structural revision of methylene bridged benzothieno-diazocine 2b based on results of X-ray diffraction analysis is presented. Internal rearrangement
