Studies on the Zinc-mediated Phenyl and Alkynyl addition to Carbon-heteroatom double bonds
… oxazolines derived from such precursors as mandelic acid, benzoylformic acid and ethyl oxamate were synthesized and used as chiral promoters for the reaction of a mixture of triphenylborane and diethylzinc with aromatic and aliphatic aldehydes. As a result, chiral secondary alcohols were …

Contributions to the chemistry of higher-coordinate Silicon : synthesis, structure, and stereodynamics of new Silicon(IV) complexes with SiO2N2C, SiO4C, or SiO6 skeletons
… chelate ligands derived from (S)-lactic acid, (S)-3- phenyllactic acid, or (S)-mandelic acid were synthesized and structurally characterized in the solid state (elemental analyses (C, H, N), crystal structure analyses, 15N and 29Si VACP/MAS solid-state NMR experiments) and in solution …

An investigation into the use of B-cyclodextrins as additives to effect enantiomeric separation by reversed phase HPLC.
… ibuprofen, hexobarbitone and mandelic acid as model chiral drugs. CD showed negligible retention on the stationary phase, so that chiral discrimination must arise as a result of different enantiomeric complex stabilities in the mobile phase. The effect of varying either CD or …

Investigating co-crystallisation of primary amides and carboxylic acids. Comparative analysis of Benzamide, Isonicotinamide and Nicotinamide co-crystal growth with carboxylic acid.
… to the primary amide, usually carboxylic acids. The progress with regards to the screening process for the determination of co-crystals is evident in the literature, In particular, high throughput solution growth methods and solvent drop grinding. The comparison of Isonicotinamide and …

Synthese und Untersuchung pentadentater Liganden und ihrer Lanthanoid(III)-Komplexe
… properties and are used e.g. as lewis acid catalysts in organic synthesis. The precise knowledge about interactions between ligand and Ln(III)-cation as well as the investigation of new ligand systems with low coordination numbers is of particular importance for the application of a …
