Syntheses and activities of indol-2-ylidene-ligated ruthenium-based olefin metathesis catalysts

23 February 2022, Version 1
Working Paper
This content is a preprint and has not undergone peer review at the time of posting.

Abstract

Here we report a new family of indol-2-ylidene (IdY)-ligated Ru-based olefin metathesis catalysts (Ru−IdY) and their X-ray crystal structures which show a unique conformation of the ruthenium environment. Catalytic activities of Ru−IdY catalysts were investigated for ring-closing metathesis, ring-opening metathesis polymerization, and ethenolysis, which show excellent turnover numbers (TONs).
