In situ modification of the Grubbs first generation catalyst: A highly controllable metathesis catalyst bearing tridentate Schiff base ligands

- A practical and inexpensive procedure for the Grubbs first generation catalyst is reported.
- A highly latent ruthenium metathesis catalytic system was reported.
- High molecular weight control in ROMP of cyclooctene was achieved.
- Reversible inhibition/activation of the catalyst were studied in RCM of diethyldiallylmalonate.
