Cross-metathesis as a versatile tool for reversible surface modifications

Cross-metathesis can be used as a versatile tool to reversibly modify support materials with molecules bearing different functionalities. Two approaches, applying cross-metathesis either inside the pore system of SBA-15 as support material or in the liquid-phase prior to immobilization on the support, have been compared. Special attention is focussed on pitfalls and limitations of surface modifications inside the pore system of support materials and on strategies to overcome these challenges. The optimized immobilization procedure was successfully transferred to the reversible immobilization of a molecular catalyst.
