Journal ArticleDOI
The Copper Halide-Catalyzed Mono-Substitution of Bromine in α,-dibromoalkanes by Grignard reagents. A Reinvestigation
TL;DR: In this paper, the Grignard compounds RMgBr in THF were converted into mono-bromides R(CH2nBr) by reaction with Grignards compounds RMnBr in the presence of 5 mol % of copper(I)bromide.
Journal ArticleDOI
An efficient method for the conversion of 2-alkynyl ethers into allenic ethers and some α-substituted derivatives
TL;DR: In this article, the α-metal-lated allenic ethers RCH=C=C(M)OR′ (M is probably K) were obtained by adding water, alkyl halide, or trimethylchlorosilane.
Journal ArticleDOI
Unconventional Synthesis of Pyridines with Rare O- and S-Functionality from Lithiated Allenes and Isothiocyanates
Journal ArticleDOI
Chemistry of acetylenic ethers 91: Thioketenes from allylthio-1-alkynes: (Short communication)
Journal ArticleDOI
An improved procedure for n-ethynylpyrrole
TL;DR: In this paper, N-Ethynylpyrrole can be obtained in good overall yields by reacting pyrrole with potassium tert-butoxide and trichloroethene in tetrahydrofuran, and subsequently dechlorinating the adduct with methyllithium or n-butyllithium in diethyl ether.
