ICSYNTH – demo available; proprietary software; A computer aided synthesis design tool that enables chemists to generate synthetic pathways for a target molecule, and a multistep interactive synthesis tree; at its core is an algorithmic chemical knowledge base of transform libraries that are automatically generated from reaction databases.

The Gomberg–Bachmann reaction, named for the Russian-American chemist Moses Gomberg and the American chemist Werner Emmanuel Bachmann, is an aryl-aryl coupling reaction via a diazonium salt. [1] [2] [3] The arene compound (here benzene) is reacted with a diazonium salt in the presence of a base to provide the biaryl through an intermediate ...
Salt metathesis is often employed to obtain salts that are soluble in organic solvents. Illustrative is the conversion of sodium perrhenate to the tetrabutylammonium salt: [2] NaReO 4 + N(C 4 H 9) 4 Cl → N(C 4 H 9) 4 [ReO 4] + NaCl. The tetrabutylammonium salt precipitates from the aqueous solution. It is soluble in dichloromethane.
Spartan is a molecular modelling and computational chemistry application from Wavefunction. [2] It contains code for molecular mechanics, semi-empirical methods, ab initio models, [3] density functional models, [4] post-Hartree–Fock models, [5] and thermochemical recipes including G3(MP2) [6] and T1.

Zeise's dimer, [(η 2-C 2 H 4)PtCl 2] 2, derived from Zeise's salt by elimination of KCl followed by dimerisation. COD-platinum dichloride, (cyclooctadiene)PtCl 2, derived from platinum(II) chloride and 1,5-cyclooctadiene, is a common platinum(II) alkene complex. Many other ethylene complexes have been prepared.
Making a saline water solution by dissolving table salt in water.The salt is the solute and the water the solvent. In chemistry, a solution is defined by IUPAC as "A liquid or solid phase containing more than one substance, when for convenience one (or more) substance, which is called the solvent, is treated differently from the other substances, which are called solutes.
A salt containing reactive cations undergo hydrolysis by which they react with water molecules, causing deprotonation of the conjugate acids. For example, the acid salt ammonium chloride is the main species formed upon the half neutralization of ammonia in aqueous solution of hydrogen chloride: [2] NH 3 + HCl(aq) → [NH 4] + Cl − (aq)
Salt water chlorination is a process that uses dissolved salt (1000–4000 ppm or 1–4 g/L) for the chlorination of swimming pools and hot tubs.The chlorine generator (also known as salt cell, salt generator, salt chlorinator, or SWG) uses electrolysis in the presence of dissolved salt to produce chlorine gas or its dissolved forms, hypochlorous acid and sodium hypochlorite, which are already ...
