A new method to graft titania using Grignard reagents.

A new method to graft titania with organic groups has been developed. In contrast to common condensation based grafting methods, this method uses organometallic chemistry to bond organic groups directly at the surface. Thereby the introduction of hetero elements at the bonding interface is avoided.

Recycling of the homogeneous Co-Jacobsen catalyst through solvent-resistant nanofiltration (SRNF).

The Co-Jacobsen complex, catalysing a hydrolytic kinetic resolution, was recycled in a semi-continuous operation using a laboratory prepared polymeric SRNF-membrane.
