Activation of Reducing Agents. Sodium Hydride Containing Complex Reducing Agents. 32. NiCRAL's as Very Efficient Agents in Promoting Cross-Coupling of Aryl Halides
Nickel-containing complex reducing agents NiCRA-bpy are shown to be the first nickel reagents able to efficiently perform cross-coupling of aryl halides.The presence of KI in the reaction medium generally improves the procedure.The mechanism and influence of the structures of the substrates are discused.

F-NMR-spectroscopy for the identification of photo products generated from aromatic iodo compounds - IV
The investigation demonstrates the analytical power of F-NMR spectroscopy for the identification of isomeric substituted fluorobiphenyls.The biphenyls are formed by u.v. irradiation of iodobenzenes in aromatic solvents.A special procedure for the identification is outlined and tendencies of the results-chemical shifts and relative rates for the production of isomers-are discussed in consideration of electronic and steric substituent effects.
