Multicomponent Reaction of Benzyl Halides: Synthesis of [1,2,4]triazolo/benzimidazolo Quinazolinones [PDF]
, 2016 We demonstrated a simple, highly efficient, one-pot method to construct triazolo/benzimidazolo quinazolinones through a cascade of oxidation, Knoevenagel condensation, and Michael addition followed by cyclization and dehydration.

The continuing significance of chiral agrochemicals
Pest Management Science, Volume 81, Issue 4, Page 1697-1716, April 2025.In the time frame 2018–2023, around 43% of the 35 chiral agrochemicals introduced to the market (herbicides, fungicides, insecticides, acaricides, and nematicides) contain one or more stereogenic centers in the molecule, and almost 69% of them have been marketed as racemic mixtures of enantiomers or stereoisomers.

Rare Metals, EarlyView.ABSTRACT Rare earth elements (REEs) play an irreplaceable role in modern technology and industry. However, due to the highly similar physicochemical properties among REEs, their separation remains a significant challenge. Additionally, REEs often exist in low‐concentration solutions, making efficient REE recovery an urgent task.

Zeitschrift für Naturforschung A, 1980 Abstract Heat capacity measurements on Mn(trz)2(NCS)2 in the range 1 - 90 K are reported. A λ-anomaly is found at Tc = 3.292(6) K. From a comparison of the high-temperature specific heat to the predictions from series expansions the intralayer exchange constant is found to be J/k = 0.245(5) K.
