DOI: 10.1016/j.catcom.2016.12.014

Abstract: Abstract The DFT/M06-D3 method was used to investigate structures and activation free energies for a series of Hoveyda-Grubbs-like catalysts with the isopropoxybenzene part replaced by coumarin (2H-chromen-2-one) and ten derivatives of isopropoxycoumarin. Out of ten… read more here.

DOI: 10.1021/acs.organomet.4c00178

Abstract: Ruthenium based Grubbs metathesis has become a commonplace reaction for synthetic chemists. Development of new generations of catalysts evolving from Grubbs I (GI) have led to greater stability, functional group compatibility, and superior reactivities. However,… read more here.

DOI: 10.3103/s1066369x20120063

Abstract: We consider one-sided Grubbs's statistics for a normal sample of the size n. These statistics are extreme studentized deviations of the observations from the sample mean. One abnormal observation (outlier) is assumed in the sample,… read more here.

Unprecedented Multifunctionality of Grubbs and Hoveyda–Grubbs Catalysts: Competitive Isomerization, Hydrogenation, Silylation and Metathesis Occurring in Solution and on Solid Phase

DOI: 10.3390/catal7040111

Abstract: This contribution showcases the interplay of several non-metathetic reactions (isomerization, silylation and “hydrogen-free” reduction) with metathesis in systems comprising a functionalized olefin and a soluble or resin-immobilized silane. These competing, one-pot reactions occur under activation… read more here.
