Formation of 6,8-di-tert-butyl-3,4-dihydro-4,4-dimethyl-1-phosphanaphthalene by the reaction of 2,2-dibromo-1-(2,4,6-tri-tert-butylphenyl)-1-phosphaethene with butyllithium

Sterically crowded 1-bromo-2-(2,4,6-tri-tert-butylphenyl)-
2-phosphaethenyllithium gave
6,8-di-tert-butyl-3,4-dihydro-4,4-dimethyl-1-phosphanaphthalene
by intramolecular insertion of an intermediary phosphinidene carbene
species into one of the C–H bonds of the two o-tert-butyl
groups.
通过分子内将中间碳化膦插入到两个邻叔丁基的一个 C-H 键中,产生了 1-溴-2-(2,4,6-三叔丁基苯基)-2-磷杂环丁烷锂,从而得到了 6,8-二叔丁基-3,4-二氢-4,4-二甲基-1-磷杂萘。
