Abstract Derivatives of 9, 10-dihydro-9-boraanthracene were synthesized from o, óbis (bromomagnesio) diphenylmethane and substituted dichloroaminoboranes. Chemical elimination experiments did not lead to 9-boraanthracene. This compound. which possibly is aromatic in character was easily formed, however, from dihydro precursors under electron impact.
