一般描述

特戊酸铯是一种有机碱，由于其在有机溶剂中的可溶性，广泛用于钯催化的交叉耦合和羰基化反应。

应用

特戊酸铯可作为碱用于合成：
  • 芴-9-酮衍生物，通过钯催化环羰基化 邻-卤代联芳基。
  • 稠合杂环（二氢苯并呋喃和二氢吲哚）由 邻-溴苯酚和苯胺前体通过Pd催化两个C(sp3)-H键的分子内偶联得到。
  • 含有季 β-碳原子的酰胺和酯类衍生物，通过Pd催化的C-H活化和氨基/烷氧基羰基化反应制备。
它还可以作为碱用于钯催化的Mizoroki-Heck 反应.

The synthesis of various substituted fluoren-9-ones has been accomplished by a novel palladium-catalyzed cyclocarbonylation of o-halobiaryls. The cyclocarbonylation of 4'-substituted-2-iodobiphenyls produces very high yields of 2-substituted fluoren-9-ones bearing either electron-donating or electron-withdrawing substituents. 3'-Substituted 2-iodobiphenyls afford in excellent yields with

The intramolecular coupling of two C(sp3 )-H bonds to forge a C(sp3 )-C(sp3 ) bond is enabled by 1,4-Pd shift from a trisubstituted aryl bromide. Contrary to most C(sp3 )-C(sp3 ) cross-dehydrogenative couplings, this reaction operates under redox-neutral conditions, with

The 1,4-palladium shift strategy allows the functionalization of remote C-H bonds that are difficult to reach directly. Reported here is a domino reaction proceeding by C(sp3 )-H activation, 1,4-palladium shift, and amino- or alkoxycarbonylation, which generates a variety of amides

Pd-catalyzed arylation or benzylation of nitroazoles using aryl sulfonates or benzyl acetates is described. Electronically varied aryl tosylates and mesylates, as well as benzyl acetates, afford the arylated and benzylated products. Arylation of nitrobenzene is also reported. The relative rate
