B(MIDA)-Containing Diborons

Unsymmetrical B(MIDA)-containing diborons of potential synthetic utility were found to be synthesized from the readily available (neop)B–B(neop) and (HO)2B–B(OH)2, and the procedure was extended to the generation of symmetrical (MIDA)B–B(MIDA). NMR and X-ray crystal structure studies revealed that B(MIDA) units of all of the diborons obtained in this study were in rigid tetrahedral environment.
