Description

Application

• Bulky NHC ligand results in faster initiation than the Grubbs 2^nd Generation Catalyst.
• Has enabled lower catalyst loadings in some applications.

Grubbs Catalyst^® M2a SIPr is a second generation Grubb′s catalyst used to catalyze olefin metathesis which low catalyst loading. This is also used in synthesizing variety of highly active second generation fast-initiation Hoveyda type ruthenium catalysts.
