Ate complexes, formation

Grignard reagent, which favor ate complex formation in equilibrium as determined by NMR spectroscopy. The reaction tolerates ester functions. [Pg.200]

Of particular interest is the process shown in equation (22), in which the ( )-alkene geometry of (20) precludes intramolecular ate complex formation and hence an addition-cyclization reaction occurs to give the a-unsubstituted carbanion (21), which may be tnqrped by protonation, deuteration or alkylation. ... [Pg.493]

HMPA can have large effects on equilibria. Phenyllithium reacts with Diphenylmercury, Diphenyl Ditelluride, and iodobenzene in THF to form ate complexes. In THF/HMPA the ate complex formation constants are dramatically higher than in THF. ... [Pg.207]
