Mechanistic investigation of human cytochromes P450 involved in hormone biosynthesis
… reaction proceeds through a non-conventional hemiketal intermediate. However, it remains unknown if the alternate substrate, 17-hydroxy-progesterone (OH-PROG) is transformed to androstenedione via this novel mechanism, by the traditional compound I (Cpd I) mechanism, or by a combination of the …

Resonance Raman spectroscopy in the analysis of residual lignin and other unsaturated structures in chemical pulps
… carbonyls exist in hydrate, hemiacetal and/or hemiketal forms. It was also shown that these structures interconvert upon drying and wetting of the pulps. UVRRS was efficient in detecting extremely low contents of carbonyls, unlike IR spectroscopy, which did not detect any differences in the …

The Colloidal Stabilization of Quantum Dots: Towards Manufacturable, Efficient Solution-Processed Solar Cells
… a new ink strategy, which I term cleavable hemiketal ligands. This novel two-component ligand strategy enables the combination of colloidal stabilization (via this longer two-component ligand) and cleavability (enabling excellent packing in film and, ultimately, excellent electronic …

Some chemistry of orthomanganated ketones
… by-product from the oxidation of (4), the cyclic hemiketal, (36), was identified by X-ray crystal structure analysis, and one other product, the lactone, (37) was identified spectrally. Determination by ¹H-NMR of the ratio of the 3-deuterio- (1a) to 3-protio- (1) formed in the orthometallation of …
