TL;DR: The tris(acetylacetonato)rhodium(III) catalyst is shown to be a versatile catalyst in the presence of DABCO (1,4-diazabicyclo[2.2]octane) as ligand for the α-alkylation of ketones followed by transfer hydrogenation, for the one-pot β-alkyation of secondary alcohols with primary alcohols and for the alkylation of aromatic amines in the absence of an inorganic base in toluene as discussed by the authors.

TL;DR: In this paper, the authors report a concise, versatile, and practical method for PhI(OCOCF3)2 mediated direct ortho C-H monoarylation of 2-phenylpyridine and its derivatives via Ru catalyzed reaction.

TL;DR: In this paper, the easy to prepare dimeric bis(?-iodo)bis[(-)-sparteine]- dicopper ([CuI{]-spa}] 2 complex is shown to be versatile catalyst for O-arylation and O-alkylation with various aryl halides with phenols and aliphatic alcohols respectively, including less reactive chlorides, such as chlorobenzene under mild conditions.

TL;DR: The use of structurally well-defined chiral chiral [CuCl 2 (sparteine) 1 and [NiCl 2(sparteines) 2 complexes as catalysts under fluoride anion-promoted double catalytic activation (DCA) conditions caused enantioreversal in the asymmetric Mukaiyama aldol reaction of 1-phenyl-1-trimethylsiloxyethylene with various aromatic aldehydes as mentioned in this paper.

TL;DR: Pregosin's complex Ru(H)(p-cymene)((R)-DTBM-Segphos)(SbF6) has been shown to be an efficient catalyst for stereoselective asymmetric hydrogenation of 2-benzamido-methyl-3-oxobutanoate to syn-(2S,3R)-methyl-2-(benzamide-methyl)-3-hydroxybutanoate in ethanol as mentioned in this paper.
