Olefin cross-metathesis, a mild, modular approach to functionalized cellulose esters†
Olefin cross-metathesis has been demonstrated to be a modular pathway for synthesis of a series of functionalized cellulose esters. As a proof of concept, cellulose acetate was acylated with two terminally olefinic acid chlorides, pent-4-enoyl chloride and undec-10-enoyl chloride, providing olefin-terminated cellulose esters with different side-chain lengths. These ω-unsaturated cellulose ester...
متن کاملCross-dressing proteins by olefin metathesis.
metathesis of proteins under aqueous conditions, which makes a powerful reaction in organic and polymer chemistry potentially available for the elaboration of biopolymers. The work by Davis and colleagues raises two follow-up questions regarding the versatility of the metathesis approach and its implementation under physiological conditions. The present study tests metathesis of proteins on a r...
متن کاملTemplate-directed olefin cross metathesis.
[reaction: see text] A template containing two secondary dialkylammonium ion recognition sites for encirclement by olefin-bearing dibenzo[24]crown-8 derivatives has been used to promote olefin cross metatheses with ruthenium-alkylidene catalysts. For monoolefin monomers, the rates of metatheses and yields of the dimers are both amplified in the presence of the template. Likewise, for a diolefin...

متن کاملMultiple Olefin Metathesis Polymerization That Combines All Three Olefin Metathesis Transformations: Ring-Opening, Ring-Closing, and Cross Metathesis.
We demonstrated tandem ring-opening/ring-closing metathesis (RO/RCM) polymerization of monomers containing two cyclopentene moieties and postmodification via insertion polymerization. In this system, well-defined polymers were efficiently formed by tandem cascade RO/RCM reaction pathway. Furthermore, these polymers could be transformed to new A,B-alternating copolymers via a sequential cross me...
