A heterobimetallic tetrahedron from a linear platinum(II)-bis(acetylide) metalloligand
Beilstein Journal of Organic Chemistry, 2020 Employing 4-ethynylaniline as a simple organic ligand we were able to prepare the stable trans-bis(acetylide)platinum(II) complex [Pt(L1)2(PBu3)2] as a linear metalloligand.

A Practical Method for the Stereochemical Analysis of Acyclic Terpenoid Carbonyl Compounds
CHIMIA, 1989 The stereoisomeric composition of acyclic terpene aldehydes and ketones can be assayed by derivatization with L(+)-diisopropyl tartrate and separation of the ensuing acetal diastereomers by gas chromatography.

Angewandte Chemie International Edition, EarlyView.An anomeric amide‐enabled divergent aldehyde functionalization sequence provides one‐pot access to unsymmetrical ureas, carbamates, thiocarbamates, thioesters, and amides. Key to this transformation is the formation of N‐Boc‐hydroxamate intermediates, which serve as platforms for orthogonal activation via Lossen‐type rearrangements, single‐electron ...

Journal of the American Oil Chemists' Society, EarlyView.ABSTRACT Saturated fatty acids (SFAs) are generally regarded simply as being resistant to oxidation compared with unsaturated fatty acids. However, it has long been reported that SFAs can undergo oxidation when heated at high temperatures, leading to the formation of unique degradation products such as 2‐alkanones and lactones.

Ultra-high resolution separation of diastereomers on carbon adsorption stationary phases [PDF]
Reversed-phase adsorption liquid chromatography was used to successfully resolve diastereomers in a complex mixture of low molecular weight polystyrene oligomers. The separation was achieved by incorporating a two-dimensional liquid chromatography system
