Monofunctional thio

In contrast to monofunctional (thio)urea organocatalysts, bifunctional catalyst structures enable simultaneous coordination, activation, and suitable relative orientation of both reaction components (the electrophile and the nucleophile) resulting in high... [Pg.203]

Apart from the increased catalytic efficiency, this structure design produced two positive side effects. In contrast to monofunctional (thio)ureas, which exhibit low solubility in nonpolar solvents due to intermolecular hydrogen-bonding association, tertiary amine thioureas of type 12 revealed intramolecular hydrogen bonding between the amine group and the amide protons making these (thio)ureas soluble in nonpolar reaction media such as toluene. The analysis of the X-ray crystal-... [Pg.204]
