The ruthenium catalysts are not sensitive to air and moisture, unlike the molybdenum catalysts.

Diver and Justin R. Griffiths. 22 Olefin Metathesis in Green Organic Solvents and Without Solvent Christian Bruneau and Cédric alphabetnyc.com: Hardcover. Ring-closing metathesis (RCM) is a powerful tool for the preparation of cyclic organic compounds.
This method is a powerful tool in organic synthesis and polymer chemistry, and is mainly applied in one of three ways: Ring Opening Metathesis Polymerisation, Cross Metathesis, and, importantly, Ring Closing Metathesis (RCM). RCM is particularly useful in pharmaceutical applications.
Ring-closing metathesis of dienes is an efficient way to access carbocycles and heterocycles of different sizes. 60 For example, reaction of diallyl ether 83a with the ruthenium catalyst A afforded the metathesis product, 2,5-dihydrofuran 84a as the major product.
A study of the influence of eight diverse solvents on a Grubbs II-catalysed ring-closing metathesis (RCM) reaction reveals a complex dependence of the different reaction steps on the solvent and suggests acetic acid as a useful solvent for RCM reactions.
