Tris methane sulfonate

Other methods for the preparation of cyclohexanecarboxaldehyde include the catalytic hydrogenation of 3-cyclohexene-1-carboxaldehyde, available from the Diels-Alder reaction of butadiene and acrolein, the reduction of cyclohexanecarbonyl chloride by lithium tri-tcrt-butoxy-aluminum hydride,the reduction of iV,A -dimethylcyclohexane-carboxamide with lithium diethoxyaluminum hydride, and the oxidation of the methane-sulfonate of cyclohexylmethanol with dimethyl sulfoxide. The hydrolysis, with simultaneous decarboxylation and rearrangement, of glycidic esters derived from cyclohexanone gives cyclohexanecarboxaldehyde.

From carboxyl substituted polystyrene (cf. Schemes 1.5.4.5 and 1.5.4.10) by treatment with 85% HjO in methan sulfonic acid. - Epoxides from di- and tri-subsiituted olefins. Sulfoxides and sulfones from sulfides some sulfides (penicillins, deacetoxycephalosporins) could be oxidised selectively to give sulfoxides. Stereoselectivities of epoxide or sulfoxide formation compare well with the results observed for monomeric m-CPBA.-"- -... 

The homogeneous hydrogenation of amides having at least one aromatic ring on N by H2 is catalysed by complexes prepared in situ from [Ru(acac)3], 1,1,1-tris(diphenylphosphinomethyl)-ethane (triphos), and methane sulfonic acid in THF to give corresponding amines with selectivities as high as 93%. The system is also... 

The most extensive studies of plasma-polymerized membranes were performed in the 1970s and early 1980s by Yasuda, who tried to develop high-performance reverse osmosis membranes by depositing plasma films onto microporous poly-sulfone films [60,61]. More recently other workers have studied the gas permeability of plasma-polymerized films. For example, Stancell and Spencer [62] were able to obtain a gas separation plasma membrane with a hydrogen/methane selectivity of almost 300, and Kawakami et al. [63] have reported plasma membranes... 

Fig. 9a and b. TBA spectra for a series of isothermal cures showing changes in (a) the relative rigidity and (b) the logarithmic decrement vs. time. Gelation and vitrification are evident in the 80, 125 and 150 °C scans, but only vitrification is observed in the 200 and 250 °C scans. The system studied was a trifunctional epoxy resin, XD7342 [triglycidyl ether of tris(hydroxyphenyl)-methane, Dow Chemical Co.], cured with a tetrafunctional aromatic amine, DDS (diamin iphenyl sulfone, Aldrich Chemical Co.)...
