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

Article abstract of DOI:10.1021/jo00383a006

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
