Abstract
2,3,4,7-Tetrahydro-1H-inden-2-ol (1) has been synthesized by Birch redn. of indan-2-ol. A single-crystal x-ray structure anal. of 1 shows the compd. to exist as hydrogen-bonded polymers along the c-axis due to the presence of a series of hydrogen-bonds between hydroxo functions. The ferrocene ester derivs., ferrocene carboxylic acid 2,3,4,7-tetrahydro-1H-inden-2-yl ester (2) and ferrocene carboxylic acid indan-2-yl ester (3) have been prepd. by peptidic coupling of ferrocene carboxylic acid with 1 and with indan-2-ol, resp. The single-crystal x-ray structure anal. of 2 and 3 reveal in both cases the cyclopentadienyl rings to adopt an eclipsed conformation with the indenyl substituent being rotated out of the Cp ester plane by almost 90°, allowing no efficient interaction between the ?-system of the Cp ring and the indene moiety. The dienyl deriv. 2 reacts with RuCl3 · nH2O in refluxing ethanol to afford [Ru(arene)Cl2]2 (4) (arene = ferrocene carboxylic acid indan-2-yl ester) as a mixt. of isomers. [on SciFinder(R)]
