Abstract
The complex [Rh(COD)(μ-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.
