Journal ArticleDOI
Efficient Procedures for 1-Bromo-1,3-Butadiene and 2-Bromo-1,3-Butadiene
TL;DR: In this article, a mixture of Z- and E-1,4-dibromo-2-butene (90% Z-isomer) was obtained in high yields by stirring a mixture with vinylacetylene, concentrated aqueous hydrogen bromide and copper(I) bromides.
Journal ArticleDOI
Chemistry of 2H-thiopyran and derivatives IV†. Deprotonation and methylation of 2H-thieno[2,3-b]thiopyran and some derivatives
R. Gräfing,Lambert Brandsma +1 more
TL;DR: In this paper, the 2-proton of the thiopyran ring is removed to give the anion 1b, and the resulting compound 4 can be converted into the compounds 5, 6 or 7 depending on the base-solvent system.
Journal ArticleDOI
Chemistry of acetylenic ethers 74: 1‐(dialkylamino)‐1‐alkynes from 1‐alkoxy‐1‐alkynes
TL;DR: In this article, LiN-(R′)2.1-Alkynyl ethers, with R alkyl, have been converted into the corresponding yneamines, RCC-N −R′)-2, in good yields (except when R CH3) by means of lithium dialkylamides.
Journal ArticleDOI
An Efficient Procedure for the N-Vinylation of Pyrrole
TL;DR: In this article, a mixture of dimethylsulfoxide, pyrrole and potassium hydroxide was used to obtain 1-Vinylpyrrole in excellent yields.
