Alkane Metathesis Schrock

Alkane Metathesis Schrock-45
In contrast to an orbital picture for an alkene, an orbital picture for an alkylidene pi bond suggests orbital symmetry that can easily interact with the LUMO on an alkene.

Alkane Metathesis Schrock

This reaction results in a four-membered ring, called a metallacyclobutane.

Olefin metathesis, or alkene metathesis, is an important process in petroleum refining and in the synthesis of important compounds such as pharmaceuticals.

The mechanism of olefin metathesis is related to pericyclic reactions like Diels Alder and [2 2] reactions.

There are other variations, including some designed for alkyne metathesis rather than alkene metathesis.

There is also a commercially-available Schrock-Hoveyda catalyst; that one is chiral, and can be used to carry out olefin metathesis enantioselectively.

  • Alkane metathesis - Wikipedia

    Alkane metathesis is a class of chemical reaction in which an alkane is rearranged to give a longer or shorter alkane product. It is similar to olefin metathesis, except that olefin metathesis cleaves and recreates a carbon-carbon double bond, but alkane methathesis operates on a…

    Olefin metathesis has had a large impact on modern organic chemistry, but important shortcomings remain for example, the lack of efficient processes that can be used to generate acyclic alkenyl.…

  • Research The Schrock Group

    This research involves the application of metathesis reactions in organic chemistry. Most recently the research has focussed on reactions that produce as high as 99% Z products in good yields. Examples include Z -selective coupling of terminal olefins, ethenolysis, cross-metathesis, ring-closing, or alkane metathesis reactions.…

  • Alkane Metathesis by Tandem Alkane

    This Account describes systems that we have developed for alkane metathesis based on the tandem operation of catalysts for alkane dehydrogenation and olefin metathesis. As dehydrogenation catalysts, we used pincer-ligated iridium complexes, and we initially investigated Schrock-type Mo or W alkylidene complexes as olefin metathesis catalysts. The interoperability of the catalysts typically.…
