Chemo-enzymatic cascade processes are invaluable due to their ability to rapidly construct high-value products from available feedstock chemicals in a one-pot relay manner. In an article, author is Baricelli, Pablo J., once mentioned the application of 533-31-3, Name is Sesamol, molecular formula is C7H6O3, molecular weight is 138.1207, MDL number is MFCD00005827, category is bromides-buliding-blocks. Now introduce a scientific discovery about this category, Quality Control of Sesamol.
Hydroformylation of natural olefins with the [Rh(COD)(mu-OMe)](2)/TPPTS complex in BMI-B(F)4/toluene biphasic medium: Observations on the interfacial role of CTAB in reactive systems
The complex [Rh(COD)(mu-OMe)](2) in presence of TPPTS (TPPTS = triphenylphosphinetrisulfonate) was evaluated as catalyst precursor for the in situ hydroformylation of natural olefins (eugenol, estragole and safrole) in biphasic media BMIm-BF4/toluene. Under moderate reaction conditions, the substrates showed the following reactivity order: eugenol > estragole > safrole. The rhodium system showed a high activity and selectivity towards the desired aldehydes. It was found that the use of cetyltrimethylammoniun bromide (CTAB) as phase transfer agent inhibits the hydroformylation reaction. The catalytic phase can be recycled up to four times without evident loss of activity or selectivity. In this work we report the use of an ionic liquid with hydrophilic character, without using water in the reaction medium.
