摘要

报告采用芳基噻蒽（aryl-TTs）代替芳基卤化物，实现了一种新颖的卡特拉尼式转化。在这一过程中，包括烷基化、胺化和氚代甲基化在内的三类正交双 C-H 功能化以及包括烯基化、氰化、甲基化、氢化和炔基化在内的五类同位操作均进展顺利。在这一转化过程中，芳基-TT 具有令人满意的反应性，其优点是可以回收离开的 TT 单元。更引人注目的是，这一发现代表了一种新的芳基-TT 化学转化方法，即通过一次化学操作实现其连续的三官能化。

Palladium/norbornene-catalyzed diversified trifunctionalization of aryl-thianthreniums†

A novel Catellani-type conversion is reported using aryl-thianthreniums (aryl-TTs) instead of aryl halides. Three classes of ortho-dual C–H functionalization involving alkylation, amination, and deuterated methylation and five types of ipso-operation including alkenylation, cyanation, methylation, hydrogenation, and alkynylation all proceed well in this procedure. In this conversion, aryl-TTs exhibit satisfactory reactivity and feature the advantage that the leaving TT unit can be recovered. More strikingly, this finding represents a new chemistry conversion of aryl-TTs, wherein contiguous tri-functionalization in a single chemical manipulation is realized.
