The Preparation of Methanesulfonic Acid | xudaphne01

Methanesulfonic acid is used as the acid electrolyte in the electroplating because many metals which are not soluble in mineral or organic acids are soluble, particularly tin and lead plating.

Sulfonic acid is one of the most important organo sulfur compounds in organic synthesis.

Methanesulfonic acid - an overview | ScienceDirect Topics

Schmidt rearrangement of optically active cyclic -keto esters with retention of configuration is effectively carried out with MsOH in the presence of (eq 13).Attempted acid-induced cyclization with MsOH of an intermediate diazo ketone involved in the synthesis of tricyclo[,10]decane-2,5,8-trione affords the corresponding methylsulfonyloxy derivative via the protonated diazonium salt (eq 14).MsOH is a useful reagent for the condensation of 2-(hydroxymethylene)cyclohexanone with sulfonamides in the presence of molecular sieves to afford products in the - diastereoisomeric forms and with >90% stereoselectivity (eq 15).The reaction of trimethylphosphine-borane with MsOH in dichloromethane gives the methanesulfonate derivative of the borane (eq 16). This compound can be condensed with diphenylphosphine-borane in the presence of to give the corresponding dimer.

Methanesulfonic acid | 814637 - Merck Millipore

We have developed an efficient method for solid phase peptide synthesis which consists of Nα-selective deprotection by dilute methanesulfonic acid, in situ neutralization, and rapid coupling reaction using benzotriazol-1-yl-oxy-tris(dimethylamino)phosphonium hexafluorophosphate or new 2-(benzotriazol-1-yl)oxy-1, 3-dimethylmidazolidinium hexafluorophosphate. This method was successfully used to synthesize several peptides using a new derivative, Boc-Tyr(Dpp) (Dpp : diphenylphosphinyl) and Boc-Arg(HCI) on a phenacylresin. For this method, we employed a fluoride ion final deprotection strategy based on a two-dimensional orthogonal protection scheme.

The report provides a basic overview of the Industrial Grade Methanesulfonic Acid Sales market including definitions, classifications, applications and market chain structure. And development policies and plans are discussed as well as manufacturing processes and cost structures.

It is the simplest of the alkylsulfonic acids

Methanesulfonic acid is convenient for industrial applications because it is liquid at ambient temperature, while the closely related p-toluenesulfonic acid (PTSA) is solid. However, in a laboratory setting, solid PTSA is more convenient. Methanesulfonic acid can be used in the generation of borane (BH3). By reacting methanesulfonic acid with NaBH4 in an aprotic solvent such as THF or DMS, the complex of BH3 and the solvent is formed. Methanesulfonic acid is considered a particularly suitable supporting electrolyte for electrochemical applications, were stands as an environmentally friendly alternative to other acid electrolytes used in plating processes. Methanesulfonic acid is also the electrolyte of choice in zinccerium (see cerium(III) methanesulfonate) and lead-acid (methanesulfonate)flow batteries.
