要旨:
Not a reductive rupture, but a strengthening of he result of the reduction of the dialane 1 with lithium. The salt isolated after addition of TMEDA contains the radical anion of 1, in which. as results of an X-ray structural analysis show, the Al-C bonds are distinctly longer (+ 0.06 angstrom) and the Al-Al bond considerably shorter (0.13 angstrom) than in 1 itself. These findings are in accord with results of MO calculations, which indicate a stabilization of the Al-Al bond by the additional electron.
