Abstract Derivatives of 10-phenyl-9, 10-dihydro-9-boraanthracene were synthesized from tris (2-benzhydrylphenyl) boroxin by pyrolysis with lithium aluminum hydride and tributyl borate. 10-Phenyl-9-boraanthracene could not be obtained from a chemical reaction or on electron impact. The isolation of lithium 9-mesityl-10-phenyl-9-boraanthracene as a crystalline non-solvated salt is described.
