Synthesis of 5-acetoxymethyl- and 5-hydroxymethyl-2-vinyl-furan.
5-Acetoxymethyl- and 5-hydroxymethyl-2-vinylfuran were synthesized by two routes. The first route starts from 2-methylfuran and the second from furfuryl acetate. The latter route, involving successive Vilsmeier-Haack and Wittig reactions, is suitable for producing 5-acetoxymethyl-2-vinylfuran and 5-hydroxymethyl-2 vinylfuran in 68% and 60%yields, respectively.

In the title compound, C(24)H(29)N(3)O(2), the dihedral angle between the benzene and pyrazole rings is 80.55 (7)°. The mol-ecule contains an acrylonitrile moiety and exists in an E conformation. Bioassay tests showed that the title compound exhibited higher acaricidal activity than its Z isomer.
متن کاملVinyl and ring-opening metathesis polymerization of norbornene with novel half-sandwich iridium(III) complexes bearing hydroxyindanimine ligands.
Half-sandwich iridium complexes bearing hydroxyindanimine ligands were synthesized and employed as catalysts for the ROMP and vinyl-type polymerization of norbornene in the presence of methylaluminoxane (MAO).
متن کاملAqueous DMSO Mediated Conversion of (2-(Arylsulfonyl)vinyl)iodonium Salts to Aldehydes and Vinyl Chlorides.
Vinyl(aryl)iodonium salts are useful compounds in organic synthesis but they are under-utilized and their chemistry is under-developed. Herein is described the solvolysis of some vinyl(phenyl)iodonium salts, bearing an arylsulfonyl group, in aqueous DMSO leading to aldehyde formation. This unusual process is selective and operates under ambient conditions. Furthermore, the addition of aqueous H...
متن کاملSurface-initiated ring-opening metathesis polymerization of 5-(perfluorohexyl)norbornene on carbon paper electrodes.
Hydrophobic coatings on carbon paper electrodes are known to provide effective water management, superior gas transfer, and improved mechanical stability of the paper in fuel cell applications. Here, we describe the surface-initiated ring-opening metathesis polymerization (ROMP) of 5-(perfluorohexyl)norbornene (NBF6) to prepare fluorocarbon-rich films on carbon paper substrates that were pre-tr...
