    摘要： The invention is a method of synthesizing Arylsulfur Trifluorides, such as Fluolead, by reacting BR2 and KF (or suitable alkali metal fluoride) in acetonitrile (or other suitable solvent). The invention also comprises using the Fluolead (or its substitutes), thus prepared, in situ as deoxofluorination reagents with a suitable aldehyde, ketone, or alcohol such as one selected from the group consisting of benzaldehyde Benzaldehyde, p-Bromobenzaldehyde, p-Tolualdehyde, Acetophenone, 2-Butanone, or Isobutyraldehyde, wherein the mixture is heated to reflux until completion. The respective products are then isolated after extraction by hexane and destruction of the sulfinyl fluoride co-product.

    摘要： A layer is spaced between an anode and a cathode and is composed of an organic compound represented by the following general formula [1]. wherein R1 to R10 are each independently a hydrogen atom, a halogen atom, a substituted amino group, an alkyl group, an aryl group, and a heterocyclic group; and X represents (a) an alkylene group having 2 to 6 carbon atoms, wherein in the alkylene group, one or separate two methylene groups may be substituted by —O—, —CO—, —CO—O—, —S—, or —NRa1—, and a hydrogen atom may be substituted by a linear, branched, or cyclic alkyl group having 1 to 10 carbon atoms, (b) an aryl group which may be substituted, or (c) a heterocyclic group which may be substituted, or (d) a fluorine atom.
