Lead-Halide Perovskites for Photocatalytic α-Alkylation of Aldehydes

open access: yesJournal of the American Chemical Society, 2019
Cost-effective and efficient photocatalysis are highly desirable in chemical synthesis. Here we demonstrate that readily prepared suspensions of APbBr3 (A = Cs or methylammonium (MA)) type perovskite colloids (ca.

Determination of Oxidized Lipids in Commonly Consumed Foods and a Preliminary Analysis of Their Binding Affinity to PPARγ

open access: yesFoods, 2021
Foods rich in poly unsaturated fatty acids (PUFA) are vulnerable to oxidation. While it is well established that endogenously derived oxidized lipids are ligands of the transcription factor PPARγ, the binding ability of diet-derived oxidized lipids is ...

A method of mild deoxydichlorination of aldehydes catalyzed by Triphenylphosphine oxide

open access: yesChimica Techno Acta, 2022
The catalytic system of triphenylphosphine oxide and phthaloyl dichloride catalysing conversion of aldehydes to 1,1-dichlorides is reported. The reaction proceeds via a P (V) catalysis manifold in which triphenylphosphine oxide turnover is achieved using
