Pd-catalyzed monoselective ortho -C-H alkylation of N -quinolyl benzamides: Evidence for stereoretentive coupling of secondary alkyl iodides
We report a method for the monoselective alkylation of ortho-C-H bonds of N-quinolyl benzamides with both primary and secondary alkyl halides under palladium catalysis. With promotion by NaHCO3 and (BnO)2PO2H or (PhO)

Rotational Barriers of Bis(2,6-disubstituted-aryl) Ketones and Bis(2,6-disubstituted-aryl)methanes and -ethanes and Their Mono- and Bis(tricarbonylchromium) Complexes
Bis(2,6-dialkylphenyl)methanes and -ethanes and bis(2,6-dialkylphenyl) ketones and their mono- and bis(tricarbonylchromium) complexes have been prepared and their variable-temperature NMR spectra recorded.Monocomplexation increases the isomerization barri
