A practical Pd-catalyzed carbonylation of (hetero)aryl bromides using a crystalline carbon monoxide (CO) surrogate, 2,4,6-trichlorophenyl formate (TCPF), was developed. This reaction proceeds without the slow addition technique that was previously required and with a low catalyst loading (1 mol%). The utility of this Pd-catalyzed external-CO-free carbonylation using TCPF was demonstrated in the synthesis
开发了一种实用的钯催化的(杂)芳基溴化物的结晶,使用结晶一氧化碳(CO)替代物2,4,6-三氯苯基甲酸(TCPF)。该反应在没有先前需要的缓慢添加技术且催化剂负载量低(1mol%)的情况下进行。在组蛋白脱乙酰基酶抑制剂的合成中证明了使用TCPF进行Pd催化的外部无CO羰基化的实用性。
