Usage

General Description

Eicosylbenzene is a hydrocarbon compound that is commonly used as a standard for gas chromatography (GC) analysis. It belongs to the group of alkenes, which are organic compounds consisting of carbon and hydrogen atoms. Eicosylbenzene is a long-chain alkylbenzene, meaning it has a 20-carbon chain attached to a benzene ring. In GC analysis, eicosylbenzene is used as a reference substance to calibrate and evaluate the performance of the chromatographic system. Its use as a standard allows for the accurate identification and quantification of other relevant compounds in a given sample. Eicosylbenzene is also used as a reference material for the analysis of petroleum products and environmental samples.

Stille cross-coupling of activated alkyltin reagents under "ligandless" conditions

(Chemical Equation Presented) Monoalkyltins activated by a fluoride source are shown to be as reactive as their vinyl or aryl homologues in the Stille coupling reaction, thus providing an easy entry into the pallado-catalyzed formation of Csp3-Csp2 bonds. In addition to this uncommon reactivity, this methodology holds several advantages such as (i) a quantitative preparation of stable and easy to handle alkyltin reagents 2, (ii) a simplified coupling procedure without any phosphine added ligand under neutral conditions, and (iii) a facile purification step of the organic products from the inorganic nontoxic tin byproducts.
