synthesizing acetylenic derivatives of 1,4-dioxane in high yield by the interaction of glycidyl ethers of acetylenic alcohols with ethylene bromohydrin in the presence of boron trifluoride etherate. Dehydrobromination of the corresponding bromohydrin was then carried out in the presence of metallic sodium in absolute diethyl ether. Acetylenic derivatives of 1,4-dioxane enter into hydrosilylation, aminomethylation
在三氟化硼醚化物的存在下,通过炔属醇的缩水甘油醚与乙烯溴醇的相互作用,已经显示出以高收率合成1,4-二恶烷的炔属衍生物的可能性。然后在无水乙醚中在金属钠存在下,进行相应的溴代醇的脱氢溴化反应。1,4-二恶烷的乙炔衍生物进入氢化硅烷化,氨甲基化和二烯缩合反应,形成新的1,4-二恶烷衍生物。
