Aryllithium compounds dimers

Similarly to compound 164, sterically crowded aryllithium compounds such as 167 crystallize with the lithium atoms 7i -coordinated to aromatic rings. Compound 167b crystallizes as a dimer, with the lithium atoms coordinated to one of the phenyl substituents... [Pg.360]

Reich and coworkers have extended their studies of aryllithium compounds by use of pendant potential ligands28. They have identified equilibria between monomers and three kinds of internally solvated bridged dimers using a combination of 13C, 6Li and 15N NMR... [Pg.32]

Cu(N03)2. Alkyl- and aryllithium compounds can be dimerized by transition-metal halides in a reaction similar to 14-24. Triarylbismuth compounds ArsBi react with palladium(O) complexes to give biaryls ArAr. Diethylzinc reacted with Ph2l BF4 in the presence of palladium acetate, to give biphenyl. ... [Pg.989]

Dimeric aryl derivatives of Cr form by reactions of aryllithium compounds with CrCls. Chromium(II) products are formed from p-dimethylaminophenyl, o-anisole, and o-oxyphenyllithium reagents ... [Pg.132]
