The invention relates to a method of forming an olefin from a first olefin and a second olefin in a metathesis reaction, comprising step (i): 

Metathesis catalysts and reactions using the catalysts

The invention relates to immobilized metal alkylidene catalysts. The catalysts are useful in olefin metathesis. 

Immobilized metal alkylidene catalysts and use thereof in olefin metathesis

A method is provided of forming an olefin from a first olefin and a second olefin in a metathesis reaction, comprising reacting the first olefin with the second olefin in the presence of a compound that catalyzes the metathesis reaction such that the molar ratio of the compound to the first or the second olefin is from 1:500 or less, and the conversion of the first or the second olefin to the olefin is at least 30%.

The invention relates to a method of forming an olefin from a first olefin and a second olefin in a metathesis reaction, comprising step (i): (i) reacting the first olefin with the second olefin in the presence of a compound that catalyzes said metathesis reaction such that the molar ratio of said compound to the first or the second olefin is from 1:500 or less, and the conversion of the first or the second olefin to said olefin is at least 50%, characterized in that as compound that catalyzes said metathesis reaction a compound of formula (A) is used: wherein M is Mo or W; Ris aryl, heteroaryl, alkyl, or heteroalkyl; optionally substituted; Rand Rcan be the same or different and are hydrogen, alkyl, alkenyl, heteroalkyl, heteroalkenyl, aryl, or heteroaryl; optionally substituted; Ris alkyl, alkoxy, heteroalkyl, aryl, heteroaryl, silylalkyl, silyloxy, optionally substituted; and Ris a residue R&#x2014;X&#x2014;, wherein X&#x2550;O and Ris aryl, optionally substituted; or X&#x2550;S and Ris aryl, optionally substituted; or X&#x2550;O and Ris (R, R, R)Si; wherein R, R, Rare alkyl or phenyl, optionally substituted; or X&#x2550;O and Ris (R, R, R)C, wherein R, R, Rare independently selected from phenyl, alkyl; optionally substituted; and to the catalysts used in the method.
