Gold(I)-catalyzed formation of furans by a Claisen-type rearrangement of ynenyl allyl ethers
Beilstein Journal of Organic Chemistry, 2011 A series of ynenyl allyl ethers were rearranged into polysubstituted furans in the presence of a gold(I) catalyst. It is proposed that the transformation involves a Claisen-type rearrangement that allows the efficient creation of quaternary centers under

Revista Facultad de Ingeniería Universidad de Antioquia, 2005 The aim of this study was to evaluate the influence of dioxins in the emission levels to the atmosphere by using some waste materials, such as used tires or meat meal, as secondary fuel during the production of clinker. For this purpose, three different

Tunable Oleo-Furan Surfactants by Acylation of Renewable Furans
ACS Central Science, 2016 An important advance in fluid surface control was the amphiphilic surfactant composed of coupled molecular structures (i.e., hydrophilic and hydrophobic) to reduce surface tension between two distinct fluid phases. However, implementation of simple surfactants has been hindered by the broad range of applications in water containing alkaline earth ...

Angewandte Chemie, EarlyView.σ‐Decoupled C9 fluorene‐framework topology control enables narrowband red MR emitters. SF‐BNO and PF‐BNO share the same BNO core, but differ in closed/open fluorene ring closure. SF‐BNO improves steric shielding and stability, while PF‐BNO enhances PLQY, orientation, and efficiency. Ex‐PSF and TE‐OLED architectures deliver ultra‐low efficiency roll‐off

Gold(I)-Catalyzed Synthesis of Highly Substituted Furans
, 2016 Cationic triphenylphosphinegold(I) complexes are excellent catalysts for a cascade reaction of propargyl-Claisen rearrangement and heterocyclization to synthesize tri- and tetrasubstituted furans. Starting from easily accessed propargyl vinyl ethers, the
