In this compilation, the authors begin by highlighting the recent developments in asymmetric 1,4- and 1,2- additions to α, β-unsaturated carbonyl compounds. The recent finding of Cu (I)-catalyzed asymmetric 1,2-addition of Grignard reagents to α, β-unsaturated carbonyl compounds, as well as aromatic ketones, has categorically revolutionized catalytic asymmetric reactions.This compilation also aims to use the well-known coordination preference of zinc in phthalocyanine and porphyrin ligands in correlation with supramolecular systems. The light-absorption process in dye-sensitized solar cells is studied using the time-dependent density functional theory.In recent years, a series of investigations on detonation wave formation in acetylene have been published. In these studies, it was shown that the formation of detonation proceeds entirely due to the energy released during the condensation of carbon nanoparticles during the growth of poly-aromatic hydrocarbons. The results of these studies are summarized and practical applications are discussed.The authors discuss aromatic amines, derivatives of aromatic hydrocarbons containing an amino group/an amine group/nitrogen atom in their structures. These compounds represent one of the most important classes of industrial and environmental chemicals. Three groups have been studied: monocyclic, polycyclic, and heterocyclic aromatic amines, which are used as intermediates in azo dye manufacturing, pigments, drugs, antibiotics, antidepressants, pesticides, and other industrial products.In the closing study, the GC-MS/MS method has been developed for the determination and quantification of 35 multiclass pesticide residues in chili samples. Pesticides were selected from different families including organochlorines, organophosphorus, carbamates, pyrethroids, triazines, triazoles, and pyrazoles. The QuEChERS-dSPE method was used for the extraction of pesticide residue.

This new and important book presents recent advances in organometallic chemistry which is based on the reactions and use of a class of compounds (R-M) that contain a covalent bond between carbon and metal. They are prepared either by direct reaction of the metal with an organic compound or by replacement of a metal from another organometallic substance. Research in organometallic chemistry is also conducted in the areas of cluster synthesis, main-group derivatives in unusual oxidation states, organometallic polymers, unstable organometallic compounds and intermediates in matrices, structure determination of organometallic compounds in the solid state [X-ray diffraction] and gaseous states [electron diffraction], and mechanisms of reactions of transient silylenes and related species. In addition to the traditional metals and semimetals, elements such as selenium, lithium and magnesium are considered to form organometallic compounds, e.g. organomagnesium compounds MeMgI, iodo(methyl)magnesium and diethylmagnesium which are Grignard reagents an organo-lithium compound BuLi butyllithium; Organometallic compounds often find practical use as catalysts, the processing of petroleum products and the production of organic polymers.
