Borabicyclo[3.2.0]heptadiene: A Fused Bicyclic Isomer of Borepin
2018
: A new isomer of borepin, identified as 2-borabicyclo[3.2.0]hepta-3,6-diene by single-crystal X-ray diffraction and heteronuclear NMR spectroscopy, was obtained by reaction of 1-mesityl-2,3,4,5-tetraphenylborole with the diaminoalkyne bis(piperidyl)acetylene. Analogous reactions of the alkyne with other borole derivatives generated seven-membered borepins, in which a second equivalent of the alkyne was found to insert into the exocyclic B-C bond. Results of mechanistic DFT studies as well as differences in the reactivity of the boroles toward the diaminoalkyne are discussed.
