Dangerous Goods

CAS number:110-65-6    molecular formula:C4H6O2

overview

compound introduction

易吸湿。化学性质活泼。易溶于水、酸性溶液、醇和丙酮,不溶于苯和醚。中等毒,半数致死量(大鼠,经口)104mg/kg。能刺激皮肤。固体丁炔二醇在空气中易潮解,有毒,具有二元伯醇的化学性质,还可进行加成反应。 丁二烯合成的中间体,腐蚀抑制剂,电镀光亮剂,聚合催化剂,脱叶剂,氯烃稳定剂。 应用: 2-丁炔-1,4-二醇被广泛用于环加合反应,如同系化方法用于制备取代的并苯、铑和铱催化[2+ 2+ 2]的分子间和分子内环三聚的。 它还可用于(−)-异丙烯、(−)-amphidinolide P和bistramide A的全合成。 Application: 2-Butyne-1,4-diol is extensively used in the cycloaddition reactions such as the homologation method for the preparation of substituted acenes, rhodium and iridium-catalyzed [2+ 2+ 2] inter and intramolecular cyclotrimerization.It can also be used in the total synthesis of (−)-isolaurallene, (−)-amphidinolide P and bistramide A.
