Interrelation of thioethers containing conjugated systems with 6π‐electrons: (Base‐catalysed isomerisations in liquid ammonia)
TL;DR: In this article, the interrelations between thioethers of the types R1CH2CR2 = CH -C≡CSCH3 (3-en-1-yne thiohetes) are investigated.
Journal ArticleDOI
New Approach to the Synthesis of Strained Cyclic Systems: I. Iminocyclobutenes and Iminothietanes from 1,3-Dilithio-3-phenylpropyne and Methyl Isothiocyanate
Ol'ga A. Tarasova,Lambert Brandsma,Nina A. Nedolya,A. V. Afonin,Igor A. Ushakov,Lyudmila V. Klyba +5 more
TL;DR: In this article, the reaction of 1,3-dilithio-3-phenylpropyne with methyl isothiocyanate in THF-hexane at -90 to -55°C, followed by successive treatment of intermediate product with a donor of protons, superbase, and alkyl halide, yields isomeric iminocyclobutenes and iminothietanes in addition to the expected aminothiophene.
Journal ArticleDOI
A new type of base‐induced isomerisation of 1,3‐enynes; the reversal of an enyne system
TL;DR: In this article, a base-catalysed isomerization of conjugated enynes leads to the reversed enyne systems, and the preparative conversion of 1-(dialkylamino)-3-buten-1-ynes (1) into 1-(logyi-lamino]-1buten3-3-neses (2) is presented.
Journal ArticleDOI
t-Butyl Alcohol-Assisted Fission of the P-P Bonds in Red Phosphorus with Lithium in Liquid Ammonia
TL;DR: In this article, a new method of the selective generation of mono- or diphosphide anions from red phosphorus by the system Li/NH3 liq in the presence of t-BuOH has been developed.
