Tetraorganodiboroxanes R2BOBR2 (1) 2 = 1,5-cyclooctanediyl = C8H14> and aluminium trihalides AlHal3 (2) n: Hal = Cl, (2b)2: Hal = Br> eliminate halogenodiorganoboranes R2BHal (4) in yields >90percent to give crystalline, in solution and in the solid state dimeric (dihalogenoaluminiooxy)diorganoboranes (Hal2AlOBR2)2 (3xy)2 2: R = C2H5, Hal = Cl; (3ba)2: R2 = C8H14, Hal = Cl; (3ab)2: R = C2H5, Hal = Br; (3bb)2: R2 = C8H14, Hal = Br>, having two AlOAl bonds . - The X-ray analyses of (3aa)2 and (3bb)2 confirmed the four-membered AlOAlO ring with the exocyclic O-diorganoboryl groups.
