Ar) to anthracene, anthryl ethers at the C9-position of anthracene were obtained as the major products when trans-9,10-dihydro-9,10-dimethoxyanthracene was reacted (10 minutes at 75 ˚C) with various alcohols. 9-Anthryl ethers with primary, secondary, cyclic alcohols, and polyethylene glycol (PEG) were isolated in 47-73% yields under optimized conditions. It is hoped that the devised method offers a
在对蒽的亲电芳族加成反应(Ad E Ar)的研究中,当反式-9,10-二氢-9,10-二甲氧基蒽反应(10分钟)时,蒽C9位的蒽醚是主要产物。在75℃下)与各种酒精混合。在优化的条件下,以47-73%的收率分离出带有伯,仲,环状醇和聚乙二醇(PEG)的9-蒽醚。希望所设计的方法为通过将反式-9,10-二氢-9,10-二甲氧基蒽与各种醇进行酸催化的反式醚化提供一种新的合成路线来制备蒽醚。 互醚化-蒽醚-反式-9,10-二氢-9,10-二甲氧基蒽
