✦ Synopsis


The angles of twist listed in Table 1 for the radicals (3a) to ( 3 c ) , ( 3 e ) and ( 3 f ) can be estimated by comparison with those calculated for twisted benzyl radicals by the INDO method [']. The discrepancy between the experimentally determined angles of twist and those deduced from space filling models, which in the meantime we have also been able to detect in sterically hindered ally1 radicals[1o', shows that the conformation of a molecule can be determined only insuffciently on the basis of its space-filling model.

In the context of studies on bis(dialkylamino)arenes with neighbouring amino functions the title compounds 5 and 6 were synthesized. Their structures and those of the monoprotonated cations Sa and 6a were determined by X-ray analysis. The strong basicities of 5 and 6 (pKa = 11.9 and 11.8 f 0.1) are

## ray structures Indenyllithium reacts with dichlorobis(dimethylamino)diborane(4) with formation of bis(dimethylamino)bis(1-indenyl)diborane(4) which rearranges on heating to the isomer bis(dimethylamino)bis(3-indenyl)diborane(4). The "mixed" bis(dimethylamino)(1-indenyl)(3-indenyl)diborane( 4) i
