2‐Bromo‐3‐phenylinden‐1‐one 2 reacted with phenylthiourea to produce 2‐phenylimino‐8‐phenylindeno[1,2‐ d ]thiazole (heteropentalene) 4 in moderate yield and bis‐substituted‐indenyl sulfide 5 in low yield. Whereas, from the reaction of 2 with thiourea or its methyl derivative only 5 was obtained in moderate yield. Another brominated compound, dibromoacetylbenzophenone and several primary amines afforded iminoindanone derivatives 6 .
