Alkenol−Alkyne Cross Metathesis
Allyl alcohols and their homologues were used in the enyne cross metathesis to prepare hydroxy-functionalized dienes. An isomerization was found to occur under prolonged heating, and a method for conversion to (E)-diene product is also ...

Thiolate Salt Mediated Dynamic Silyl Ether Exchanges for Polymer Network Design and Deconstruction
This work introduces thiolate salts as mediators for dynamic silyl ether exchange. This platform enables the synthesis of reprocessable covalent adaptable polymer networks (CANs) and allows for sterically controlled, and tunable deconstruction of silyl ether‐containing thermosets.

Poly(vinylpyrrolidone) creates a quasi‐stable dispersion copolymerization system that enables direct comparison of the dispersed and precipitated polymer fractions. Structural analysis shows that fractionation correlates more strongly with sulfur rank than with molecular weight, revealing how the number of consecutive sulfur atoms in the polysulfide ...

Heterogeneous catalysts for olefln cross-metathesis
Olefin metathesis has been widely used in the fields of petrochemical industry and organic synthesis. It can be classified as ring-opening metathesis, ring-opening metathesis polymerization, ring-closing metathesis and cross-metathesis, etc.

Kinetics of anionic polymerization of β‐myrcene in hydrocarbon solvents
The process of anionic polymerization of β‐myrcene in hydrocarbon solvents was examined by kinetic studies and quantum chemical calculations. Abstract The kinetics of anionic polymerization of β‐myrcene initiated by sec‐butyllithium were examined in saturated and unsaturated hydrocarbon solvents, i.e. cyclohexane, cyclohexene, 4‐vinylcyclohexene and dl‐

Exploiting the cross-metathesis reaction in the synthesis of pseudo-oligosaccharides
An approach to the synthesis of pseudo-oligosaccharides based on the cross-metathesis reaction between distinct sugar-olefins, followed by intramolecular cyclization of the obtained heterodimer, is presented. In particular, the relative efficiency of two
