Journal ArticleDOI
Transition metal catalysed cross-coupling between benzylic halides and aryl nucleophiles. Synthesis of some toxicologically interesting tetrachlorobenzyltoluenes
TL;DR: In this article, the aryl-benzyl cross-coupling in the presence of copper-, nickel-and palladium-catalysts has been investigated with a number of chlorine- and methyl-substituted arylsmetal compounds ArM (M=MgBr, ZnCl) and ArCH2X.
Journal ArticleDOI

Journal ArticleDOI
Chemistry of acetylenic ethers 70: Preparation of 1‐alkynyl thioethers and 1‐alkynyl selenoethers from sodium alkynylides, sulphur or selenium and alkyl halides
TL;DR: A number of 1-alkynyl thioethers and selenoethers RCC-XR′ (XS or Se) have been prepared by reaction of sodium alkynylides, dissolved in liquid ammonia, with sulphur or selenium, followed by alkylation.
Journal ArticleDOI
Base induced reactions of 1‐alkoxy‐ or l‐methylthio‐l‐(α‐ or β‐hydroxyalkyl)allenes. Formation of 3‐alkoxy‐ and 3‐methylthiodihydrofurans
TL;DR: In this article, the preparation of 3-oxotetrahydrofuran derivatives with dilute sulfuric acid was described, and a mixture of 3methoxy-2-methyl-4,5-dihydrafurans was obtained.
Journal ArticleDOI
Synthesis of 2,3-dihydropyridines, cyclobutanopyrrolines and quinolines from lithiated allenes and isothiocyanates
Lambert Brandsma,Nina A. Nedolya,Hermann D. Verkruijsse,Noel L. Owen,Li Du,Boris A. Trofimov +5 more
TL;DR: The products obtained by Salkylation of the adducts from lithiated allenes and alkyl or aryl isothiocyanates undergo thermal rearrangements with ultimate formation of derivatives of 2,3-dihydropyridine, cyclobutanopyrroline and quinoline as discussed by the authors.
