2,3,4,7-Tetrahydro-1H -inden-2-ol: synthesis, molecular structure and coordination chemistry

چکیده
2,3,4,7-Tetrahydro-1H -inden-2-ol (1) has been synthesised by Birch reduction of indan-2-ol. A single-crystal X-ray structur analysis of 1 shows the compound 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 derivatives, ferrocene carboxylic acid 2,3,4,7-tetrahydro-1H -inden-2-yl este (2) and ferrocene carboxylic acid indan-2-yl ester (3) have been prepared by peptidic coupling of ferrocene carboxylic acid with 1 an with indan-2-ol, respectively. The single-crystal X-ray structure analyses of 2 and 3 reveal in both cases the cyclopentadienyl rings t adopt an eclipsed conformation with the indenyl substituent being rotated out of the Cp ester plane by almost 90 , allowing n efficient interaction between the p-system of the Cp ring and the indene moiety. The dienyl derivative 2 reacts with RuCl3 nH2O i refluxing ethanol to afford [Ru(arene)Cl2]2 (4) (arene1⁄4 ferrocene carboxylic acid indan-2-yl ester) as a mixture of isomers.
