The telomerization of 1,3-dienes with functionalized nucleophiles presents an atom efficient and selective synthesis of potential non-ionic surfactants. Crucial for application of these synthetic pathways is the effective recycling of the homogeneous

Long chain amines are of great importance for industrial chemistry as they are precursors for surfactants like amine oxides or quaternary ammonia compounds. The atom efficient, homogeneously catalyzed hydroamination using 1,3-dienes offers linear lin

A key challenge in the synthesis of non-ionic surfactants is the opposite polarity of the substrates and the connected challenge of using homogeneous catalysis. We present the telomerisation of β-myrcene with N-methylglucamine to C20-N-alkylated pol

Catalytic telomerization of 1,3-butadiene with alcohols is a catalytic reaction and an effective tool to synthesize 2,7-octadienyl ethers with different characteristics depending on the alcoholic substrate. While Pd/phosphine type catalysts were stud

A multistep synthesis of the planar chiral tricarbonyl(η6-indan-1,2-dione)chromium, based on acetal protection of the keto groups, is presented. Since common deacetalization procedures failed, an oxidative deprotection with triphenylcarbenium tetraf

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 deacetal

The new preparation of 1,2-dioxobenzocyclobutene ( 4 ) via a short and efficient three-step route starting from the commercially available ninhydrin represents a superior procedure to all hitherto known syntheses of this valuable compound. The photo-
