Learn More Organometallics and Organometalloids
Organometallics and organometalloids are among the most widely used compounds in modern organic chemistry. With diverse laboratory applications ranging from homogenous catalysts to stoichiometric reagents, they continue to play a vital role in research and development.
Learn More Stille Cross-Coupling Reaction
In 1976, the first palladium-catalyzed cross-coupling of organotin compounds was accomplished by C. Eaborn, et al. The next year, M. Kosugi and T. Migita described the transition metal-catalyzed cross-coupling of organotin compounds with aryl halides and acid chlorides. Following this, in 1978, J.K.
Learn More Inorganic Chemistry
Inorganics include salts, metals, and substances made from single elements. In general, they are ionic compounds consisting of cations and anions joined by ionic bonding, and can be classified as coordination compounds, main group compounds, transition metal compounds, organometallic compounds,...
Learn More Lubricating Oil Analysis for Trace Elements
Lubricants reduce surface frictions produced by materials in mutual contact, transfer heat, and carry away contaminants produced in the system. Liquid lubricants contains 90% base oil (often mineral oil from petroleum, but occasionally synthetic oils) and less than 10% additives.
Learn More Petrochemical Analysis by ICP-OES
The petrochemical industry widely uses Inductively Coupled Plasma-Optical Emission Spectroscopy (ICP-OES) for the analysis of trace elements during extraction and refining of crude oil, where trace elements are identified and measured in drilling mud compounds, produced waters, crude oil, and in the...

Learn More Grignard Reagents
Organomagnesium halides of the general structure R-Mg-X, with R = alkyl, alkenyl or aryl and X = halogen, are called “Grignard” reagents after their inventor, chemist Victor Grignard. Grignard reagents are highly reactive and react with most organic compounds.
Learn More Heterocyclic Compounds
Heterocyclic compounds, or heterocycles, are cyclic compounds that have atoms of at least two different elements as members of the ring structure.Organic heterocycles contain one or more carbon atoms and, based on their electronic structure, are classified as saturated, unsaturated, and aromatic.

Learn More Negishi Cross-Coupling Reaction
In 1972, after the discovery of the nickel-catalyzed cross-coupling of alkenyl and aryl halides with Grignard reagents (Kumada cross-coupling), improvements in functional group tolerance were sought. It was realized that the answer lay in the use of organometallic substrates with metals less...
