Abstract
During the last two decades, organosulfur compounds have been used in the field of transition metal catalysis. Some of such compounds are known for their ability to withstand their exposure to air and moisture. These compounds are very important ligands. They may be obtained using simple and smooth modular synthetic protocols which include nucleophilic substitution reactions. The development of click chemistry represents a new era of innovation. It is a lighthouse of reliable and efficient reactions. In recent past, click chemistry has also been applied for the synthesis of such organosulfur ligands specifically suited for the dynamic field of transition metal catalysis. In order to synthesize novel compounds containing sulfur and triazole ring, click chemistry is an advantageous methodology over other approaches. This article covers the general features and uses of this methodology for the development of catalytically active organosulfur compounds. The significant advances in the design of transition metal catalytic systems utilizing such ligands, their use in the catalysis of many chemical transformations are also covered in this article. Effort has also been made to present a comparative overview of the performances of such catalysts vis-à-vis the catalysts designed commonly used ligands. Catalytic performances have been discussed thoroughly in order to identify the impact of ligand architecture on efficacy of the catalyst. Effect of reaction conditions (such as time, temperature etc.) and mechanistic aspects have also been rationalized.

Abstract
The title compound, 1-phenyl-3,3-di(1H-pyrazol-1-yl)propan-1-one, was synthesized in a 52% yield for the first time by a one-step reaction between 1H-pyrazole and 1-phenylprop-2-yn-1-one (their ratio being 2:1) in solid Al2O3 at room temperature. The product was characterized by 1H-NMR, 13C-NMR, IR spectroscopy, X-Ray diffraction and elemental analysis.

Abstract
![]()
This Review examines parts per million (ppm) palladium
concentrations
in catalytic cross-coupling reactions and their relationship with
mole percentage (mol %). Most studies in catalytic cross-coupling
chemistry have historically focused on the concentration ratio between
(pre)catalyst and the limiting reagent (substrate), expressed as mol
%. Several recent papers have outlined the use of “ppm level”
palladium as an alternative means of describing catalytic cross-coupling
reaction systems. This led us to delve deeper into the literature
to assess whether “ppm level” palladium is a practically
useful descriptor of catalyst quantities in palladium-catalyzed cross-coupling
reactions. Indeed, we conjectured that many reactions could, unknowingly,
have employed low “ppm levels” of palladium (pre)catalyst,
and generally, what would the spread of ppm palladium look like across
a selection of studies reported across the vast array of the cross-coupling
chemistry literature. In a few selected examples, we have examined
other metal catalyst systems for comparison with palladium.

Abstract
Azine-containing biaryls are ubiquitous scaffolds in many areas of chemistry, and efficient methods for their synthesis are continually desired. Pyridine rings are prominent amongst these motifs. Transition-metal-catalysed cross-coupling reactions have been widely used for their synthesis and functionalisation as they often provide a swift and tuneable route to related biaryl scaffolds. However, 2-pyridine organometallics are capricious coupling partners and 2-pyridyl boron reagents in particular are notorious for their instability and poor reactivity in Suzuki-Miyaura cross-coupling reactions. The synthesis of pyridine-containing biaryls is therefore limited, and methods for the formation of unsymmetrical 2,2'-bis-pyridines are scarce. This Review focuses on the methods developed for the challenging coupling of 2-pyridine nucleophiles with (hetero)aryl electrophiles, and ranges from traditional cross-coupling processes to alternative nucleophilic reagents and novel main group approaches.

An efficient method for synthesizing arylated heteroaromatics has been reported via Pd-catalyzed ligand-free cross-coupling of N-heteroaromatic bromides with iodine(III) reagents under mild conditions. Iodobenzene diacetate, iodosobenzene, and diphenyliodonium salts act as ideal arylated sources in this reaction, producing bioactive aromatic-substituted pyridines and quinolines in moderate to high yields.

In the presence of Pd(OAc)2 and orotic acid, various halides including aryl iodides, aryl bromides, vinyl bromides, and aryl chlorides were coupled efficiently with aryl- and vinyltin compounds to afford the corresponding biaryls and stilbenes. The high catalytic efficacy of Pd(OAc)2/orotic acid has also been demonstrated.

Abstract
We describe herein an efficient method for the synthesis of unsymmetrically-substituted biphenyls using a sonochemical variation of the Stille coupling, whose results have also been compared with the conventional silent reaction. Ultrasound significantly enhances this useful organometallic transformation affording products in higher yields and in shorter reaction times than non-irradiated reactions. The scope has been explored with a selection of arylstannanes as precursors and, remarkably, no by-products resulting from homo-coupling could be detected.
