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)borane In 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 F 2 BN(i‐C 3 H 7 ) 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 , 11 B, 13 C, 19 F) and MS data are given; for 1, 2, 5 , and 6 the X‐ray structure analyses were performed.
