This invention relates to catalyst compounds and the synthesis and applications useful in olefin metathesis reactions. The catalyst compounds of the invention are represented by the formula (I): wherein M is a Group 8 metal; X1 and X2 are anionic ligands; L1 and L2 are neutral two electron donor ligands. The present invention also relates to an easy applicable catalyst synthesis and the application in different olefin metathesis processes, e.g. Reaction Injection Molding (RIM), process to make α-olefins from fatty acid ester, e.g. methyl oleate.
We have developed an easy and practical method for the synthesis of α,β-unsaturated oximes and nitriles from readily available propargylic alcohols with hydroxylaminehydrochloride (NH2OH·HCl) under metal-free conditions. By using or not using p-toluenesulfonyl chloride (p-TsCl) as the dehydrating promoter, the desired nitriles or oximes could be obtained, respectively via a three-step one-pot or two-step

The thermal dimerization of three [n]cumulenes (n = 5, 7, and 9) has been investigated, and a common reactivity pattern is observed that gives radialenes or expanded radialenes through regioselective...
