Methods involving zincâlead exchange for the one-pot
conversion of terminal acetylenes into alk-1-ynyllead(IV)
triacetates have been developed, and examples of the in situ
C-alkynylation of a number of carbon nucleophiles are reported.
An attempt to extend the reaction to phenols by treating
2,4,6-trimethylphenol with phenylethynyllead triacetate led to formation
of the spiro dienone 16, the structure of which was determined by X-ray
diffraction.
我们开发了
锌钯交换法,用于将末端
炔烃一锅转化为烷基-1-炔基lead(IV)
三乙酸酯,并报告了一些碳亲核物原位 C- 烷炔化的实例。 通过用
苯乙炔基lead
三乙酸酯处理 2,4,6-三甲基
苯酚,尝试将反应扩展到
苯酚,结果形成了螺二烯酮 16,并通过 X 射线衍射确定了其结构。
