Abstract
A series of 1 - and 2-substituted indanes have been treated with hexacarbonylchromium in three solvents: diglyme, decalin, and cyclohexanol. The ratios of cis- to trans-tricarbonyl(indane)chromiums thus obtained have been shown to be thermodynamically controlled, as individual isomers come to equilibrium under the conditions used. The ratios are discussed in terms of non-bonded interactions between the substituent and the chromium carbonyl group. Some unusual cases of preferred stabilisation of cis-isomers have been found.
