Direct reaction of 2,2′-dilithiobibenzyl with (CH3)2MCl2 or (C6H5)2MCl2 where M Si, Ge, Sn, or Pb results in the formation of 10,11-dihydro-5H-dibenzo-[b,f]metallepins. The germanium derivaives were successfully converted to 5,5-dimethyl- and 5,5-diphenyl-5H-dibenzo[b,f]germepin by bromination followed by dehydrobromination with 1,5-diazabicyclo[4.3.0]non-5-ene. Reactions of dihydrodibenzo[b,f]stannepins uniformly gave ring cleavage products. The abundances of the metal fragments produced in the mass spectrum of the dihydrodibenzometallepins are recorded and a fragmentation pattern common to the system is given.
