The preparation of pent-2-en-4-ynylamine and pent-2-en-4-ynylthiol and their derivatives from 5-bromopent-3-en-1-yne was studied. Moreover, in connection with the preparation of the bromide, the rearrangement-bromination of vinylethynylcarbinol was found to give three isomeric bromides, 5-bromopent-trans-3-en-1-yne, 5-bromopent-cis-3-en-1-yne, and 3-bromopent-1-en-4-yne. Pent-2-en-4-ynylamine was obtained
研究了从 5-溴戊-3-烯-1-炔制备戊-2-烯-4-炔胺和戊-2-烯-4-炔硫醇及其衍生物。此外,关于溴化物的制备,发现乙烯基乙炔基甲醇的重排-溴化得到三种异构的溴化物,5-溴戊-反式-3-en-1-yne,5-溴戊-顺-3-en-1 -yne 和 3-bromopent-1-en-4-yne。Pent-2-en-4-ynylamine 由 5-bromopent-3-en-1-yne 通过两种方法获得,即六胺盐的水解和 N-(pent-2-en-4-炔基)邻苯二甲酰亚胺。5-溴戊-3-烯-1-炔与氢硫化钾反应,用醇氨分解戊-2-烯-4-炔基黄原酸乙酯,得到戊-2-烯-4-炔硫醇。
