Catalyst Screening by Multistep Synthesis

With this experimental set-up, highly active, cationic ruthenium-carbene catalysts are used in ring-opening metathesis polymerization (ROMP). Four different structural features of the catalyst [ R2P(CH2) PR2-k2P XRu=CHR]+ (the halogen 

Electrospray is a very gentle ionization procedure - originally developed for analyzis of intact proteins without denaturization loss. Thales Technologies adapted the technology to (sometimes very fragile) organometallic complexes, which can be brought into the gas phase from a solution as low as 10 6 M without decomposition. 

The first quadrupole isolates ions according to their mass to charge ratio. 

Reaction products are separated and analyzed in the second quadrupole. 

In the octapole the species selected are subjected to further catalytic reactions.
