The reactions of free radicals, formed by thermal decomposition of t-butyi peroxide, with phenols has been studied Although the major products were 2,2′-dihydroxy-derivatives of biphenyl the isomeric 2-hydoxydiphenyl ethers were also formed. Pummerer's ketone was not formed, and the isolation of 4,4′-dihydroxy-3,3′-dimethylbibenzyl from the reaction with 2,4-dimethylphenol has shown that coupling via
已经研究了由叔丁基过氧化物热分解形成的自由基与酚的反应。尽管主要产物是联苯的2,2'-二羟基衍生物,但也形成了异构体2-羟基二苯醚。没有形成Pummerer的酮,从与2,4-二甲基苯酚的反应中分离出4,4'-二羟基-3,3'-二甲基联苄表明,通过苄基的偶合不限于完全受阻的苯酚或与4-甲氧基甲苯。 。
