Polycyclic Compounds from 2,5-Norbornadiene, Isopropylbenzene, and Dehalogenation Products of Dihalogeno(diorganylamino)boranes. Reaction of Bis(diisopropylamino)phenylborane with Na/K Alloy and Difluoro(diisopropylamino)boraneIn the reaction of 2,5-norbornadiene with Na/K alloy and dichloro(diisopropylamino)borane the species 1 was isolated, which contains six boron atoms in two triborolane rings. From isopropylbenzene and the dehalogenation products of (diisobutylamino)difluoroborane the ethenodiborolodiborol system 2 was isolated. When bis(diisopropylamino)phenylborane is treated with F2BN(i-C3H7)2 and Na/K alloy the diborane(4) derivative 5 and 1,1,2,2-tetrakisborylethane (6) are formed together with bis(diisopropylamino)fluoroborane (7). NMR (1, 11B, 13C, 19F) and MS data are given; for 1, 2, 5, and 6 the X-ray structure analyses were performed.
