Chromium tricarbonyl complexes of 3-methoxybenzyl alcohol and related compounds were selectively lithiated at the 4-position in contrast to the corresponding metal free arene compounds. The resulting I-lithio complexes were converted to the I-substituted arene compounds in moderate to excellent yiel

Axially chiral N,N-diethyl 2,6-disubstituted benzamides were stereo-selectively prepared utilizing planar chiral (arene)chromium complexes as an enantiomerically active form by following two methods. Ortho-lithiation of the enantiomerically pure planar chiral tricarbonyl(N,N-diethyl 2-methylbenzamid
The positions of conformational equiliirium in disubstituted arene chromium tricarbonyl complexes, i.e. alkylanisole chromium tricmbonyl complexes and alkylbenzoate chromium tricarbonyl complexes, have been determined by 'H N M R spectroscopy. It has been found that the donor effect is the dominant
