What is Umicore M73 SIPr?
The Uses of Umicore M73 SIPr
Hoveyda-Grubbs Catalyst? M73 SIPr is a second generation fast-initiation Hoveyda type ruthenium complex used to catalyze olefin metathesis. This catalyst exhibits high initiation rate even at -20°C. It is used in catalyzing ring-opening metathesis polymerization cross metathesis (ROMP/CM) of cyclooctene and microwave assisted cross metathesis-cyclization of 1,5-hexadiene.
