Using the water-soluble N-methylglucamine and the non-polar β-myrcene in a biphasic telomerisation with the amphiphilic TPPMS ligand, new surfactants are obtained.

The syntheses and characterization of the tricarbonylchromium complexes of 1,3‐indandione and ninhydrin are described. As the direct complexation proved unsuccessful, the acetal route was tried. Although some complexes were obtained, complex deacetalization did not work in the case of ninhydrin. Finally, the oxidation of tricarbonyl(η6‐1,3‐indandione)chromium(0) with dimethyldioxirane gave the ninhydrin complex in 75% yield in equilibrium with the indantrione complex. The latter reacts in hetero Diels‐Alder reactions with dienes with diastereoselective formation of spiro anellated pyran derivatives.
