Reagent

TL;DR: The Pd2(dba)3/P(tBu)3 was found to promote the Sonogashira reaction of aryl bromides at room temperature and without CuI as the co-catalyst in high yield as mentioned in this paper.

TL;DR: Using the widely available DMSO as the formylation reagent under oxidative conditions, an efficient Cu-catalyzed C3-formylation reaction of imidazo[1,2-a]pyridine C-H bonds to directly generate structurally sophisticated 3- formyl imidaz[ 1, 2-a], 1-a-Pyridine derivatives has been developed.

TL;DR: Catalytic dehydration of aldoximes can be performed highly efficiently with a catalyst system of [RuCl(2)(p-cymene)](2)/molecular sieves under essentially neutral and mild conditions, and various types of cyano compounds are produced in good to excellent yields.

TL;DR: An ionic cobalt-PNP complex is developed for the efficient α-alkylation of ketones with primary alcohols for the first time and was successfully applied to the greener synthesis of quinoline derivatives while using 2-aminobenzyl alcohol as an alkylating reagent.

TL;DR: Magnesium oxide/phosphorus oxychloride (MOPO) was found to be an efficient reagent for the preparation of 1,5-benzodiazepine derivatives of o -phenylenediamine and ketones as discussed by the authors.
