Formation of pentaorganostannates from Bis(2-bromo-2′-biphenyl) stannanes and tert-butyllithium upon substitution of alkyl and aryl groups on tin atoms

The reaction, of bis(2-brom.o-2'-biphenyl)stannanes 1 with tert-butyllithium in the presence of diaryl- and dialkyldichlorostannanes leads to the extrusion of aryl and alkyl groups on the tin atom, affording 9-stannafluorene derivatives bearing biphenyl g

REGIOSELECTIVE DIMETALLIERUNG VON AROMATEN. BEQUEMER ZUGANG ZU 2,2'-DISUBSTITUIERTEN BIPHENYLDERIVATEN

Lithiation of biphenyl with 2.4 mol of n-butyllithium in the presence of TMEDA led directly to the 2,2'-dilithio derivative (I) in modest, but preparatively useful yields.I, in turn, was converted to a variety of products.The activation of the 2'-position of 2-lithiobiphenyl was shown directly by a separate experiment.MNDO calculations indicate stabilization in I by double bridging and in 2-lithiobiphenyl by intramolecular ? interaction of Li with the o-phenyl group.Similar interactions in substitution transition states rationalize the specificity of the reactions observed.
