The activity in alkane metathesis of tungsten complexes grafted on gamma alumina raises many questions regarding the structure of the active site and the reaction. Olefin metathesis, or alkene metathesis, is an important process in petroleum refining and in the synthesis of important compounds such as pharmaceuticals. Alkane metathesis (am) has potentially tremendous applicability via converting low-value alkanes (c3-c9) from the fisher-tropsch process into linear alkanes in the. Alkane metathesis is a reaction that transforms an alkane (cnh2n+2) or an alkane mixture into lower. Alkyne metathesis is an organic reaction involving the redistribution of alkyne chemical bonds this reaction is closely related to olefin metathesis.
Olefin metathesis grubbs reaction olefin metathesis allows the exchange of substituents between different olefins - a transalkylidenation this reaction was first. Previous article in issue: mechanical properties of polymers based on nanostructure and morphology edited by georg h michler and francisco j balta′-calleja. Alkane metathesis by tandem alkane-dehydrogenation-olefin-metathesis catalysis and related the rate of alkane dehydrogenation generally limits the.
Alkane metathesis and related reactions reported by yang wang april 7, 2011 introduction alkanes are the major. Reacting a first alkane in the presence of a dual catalyst system comprising: (i) a hydrogen transfer catalyst and (ii) a metathesis catalyst to produce said mixture. A tandem system for the metathesis of n-alkanes, comprising pincer-ligated alkane-dehydrogenation catalysts and either schrock-type or heterogeneous olefin-metathesis.
Organoiridium complexes catalyze the dehydrogenation of alkanes and alkyl groups, a transformation with tremendous potential applicability for example, alkane. Researchers have developed a cross-alkane metathesis process that breaks down polyethylene waste into liquid fuels and waxes under mild conditions.
