The flash vacuum pyrolysis of 1‐chloro‐1‐boraindane 1 leads with dehydrogenation to the 1‐benzoborole 2 . The highly reactive, antiaromatic system dimerizes regiospecifically even at low temperatures to the diboradibenzotetrahydroazulene 3 . Trapping reactions with 2‐butyne. DCl and CH 3 OD furnished products which likewise suggest intermediary occurrence of 2 .
