Branco, Luis C.; Serbanovic, Ana; Nunes da Ponte, Manuel; Afonso, Carlos A. M. published the artcile< Clean osmium-catalyzed asymmetric dihydroxylation of olefins in ionic liquids and supercritical CO2 product recovery>, Application In Synthesis of 112-63-0, the main research area is asym dihydroxylation olefin ionic liquid osmium catalyst.
The combination of ionic liquids (ILs) as solvents in the asym. Sharpless dihydroxylation (AD) with the use of scCO2 in the separation process allows a simple, efficient, clean and robust system for the reuse of the AD catalytic system, which also does not need the use of organic solvents either for the reaction or for the separation of products and allows the isolation of the diol, in high yield and enantiomeric excess and basically without contamination with osmium. The AD reaction was performed with the substrates 1-hexene and styrene, using the catalytic system consisting of (DHQD)2PHAL (1.0 mol% ) and K2OsO2(OH)4 (0.5 mol% ) and the co-oxidants K3Fe(CN)6 and N-methylmorpholine oxide (NMO). Under these conditions, a range of ILs based on the methylimidazolium (mim), dimethylimidazolium (bdmim) and tetraalkyldimethylguanidinium (dmg) cations were screened.
Chemical Communications (Cambridge, United Kingdom) published new progress about Dihydroxylation catalysts, stereoselective. 112-63-0 belongs to class esters-buliding-blocks, and the molecular formula is C19H34O2, Application In Synthesis of 112-63-0.
