Addition and Insertion Reactions of Subvalent Boron Species with Aromatic Compounds Dichloro(diisopropylamino)borane reacts with pentamethylcyclopentadienide providing the substitution product 1.A suspension of a sodium-potassium alloy in 1,2-dimethoxyethane and 1,2,4,5-tetramethylbenzene reacts with difluoro(diisopropylamino)borane to give 1,4-bis-2,3,5,6-tetramethyl-2,5-cyclohexadiene (3).If o-xylene is used instead of 1,2,4,5-tetramethylbenzene in this reaction, 1,4-bis-2,3-dimethyl-2,5-cyclohexadiene (4) is the main product; however, the bicyclic compound 5 is also formed by formal insertion of two aminoborene units "BNR2" into the carbon skeleton and by addition of two (FBNR2) units.The compounds are characterized by elemental analyses and spectroscopically .An X-ray structure analysis of 5 is presented.
