What is Substituent effects in π-(tricarbonylchromium)arenes: I. 1H NMR Spectroscopy of alkylsubstituted π-(tricarbonylchromium)benzenes about?

Some thirt.y substituted r-( tricarbonylchromium jbenzenes, including some crow-ded alkylsubstituteci complexes. e-g. (l',l'-diethylpropyl)-, (1'-t-butyl-2',2'dimethylpropyl)-, 1 .&ii-t-butyl-and 1,2,4-tri-t-butyl-;r-(tricarbonylchromium)benzenes, have been prepared-'H !VMR spectra have been recorded from acetone solutions of the complexes. Using the chemical shift increments of the aromatic protons on compks formation of C, HgCH-t-Bu2 as a reference for the eclipsed conformation with the subst,ituent. staggered with respect to the carbonyl ligands, the contribution of this conformer to the conformational equilibrium of the other monoalkylsubstituted compleses has been estimated. 'H NXIR spectroscopy turns out to be a useful probe in conformation analysis of n-(tricarbonylchromium)arenes.
