sed proton sponge 9 has been prepared by treatment of 1,8di(methylamino)naphthalene (7) with 1,8-bis(bromomethyl)naphthalene (8). Though the compound 9 is structurally related both to kinetically low-active 1,8bis(dimethylamino)naphthalene (1, parent proton sponge) and kinetically active 1,8bis(dimethylaminomethyl)naphthalene (2), X-ray and basicity studies have revealed that the proton sponge behavior
一种新的基于 1,5-二氮杂环癸烷的质子海绵 9 通过用 1,8-双(溴甲基)萘(8)处理 1,8-二(甲基氨基)萘(7)制备。尽管化合物 9 在结构上与动力学低活性 1,8 双(二甲氨基)萘(1,母质子海绵)和动力学活性 1,8 双(二甲氨基甲基)萘 (2) 相关,但 X 射线和碱度研究表明,前者的质子海绵行为占主导地位。发现 1-二甲基氨基-8-甲基氨基萘 (11) 与 8 的双烷基化仅接触 NHMe 官能团并导致 N-Me 基团的取代,产生以前未知的苯并 [de] 异喹啉质子海绵 15。 8 与 1,8-二氨基萘或 2,2 二甲基-2,3-二氢脒与其他产物一起生成,
