• related Baylis-Hillman reaction between p-nitrobenzaldehyde and methyl acrylate using the above chiral IL.[25] A slight increase in de (not optimized value) was detected when employing p-methoxyphenyl (Table 3, entry 2, R = p-MeOC6H4). ILs are highly recyclable and do not lose any of their properties even
