Room Temperature CH Activation and Cross-Coupling of Aryl Ureas in Water

Just mix in water 'n stir: Pd‐catalyzed CH activation/cross‐couplings can be carried out at roomtemperature in water/surfactant mixtures. The combination of Pd(OAc)2 and HBF4 allowed for reactions of aryl ureas with aryl iodides under very mild conditions, using micellar catalysis (see scheme). This reaction is made possible by use of an in situ generated cationic palladium catalyst.
只需与水混合并搅拌即可:Pd 催化的 C - H 活化/交叉偶联可以在室温下在水/表面活性剂混合物中进行。Pd(OAc) 2和HBF 4的组合允许芳基脲与芳基碘化物在非常温和的条件下使用胶束催化进行反应(参见方案)。通过使用原位产生的阳离子钯催化剂使该反应成为可能。
Aromaticity-Dependent Regioselectivity in Pd(II)-Catalyzed C–H Direct Arylation of Aryl Ureas

Palladium-catalyzed C–H direct arylation generally occurs on the ortho-position of directing groups. By comparing meta-arylated products of 2-naphthyl urea to ortho-arylated products of phenyl urea, the ortho- and meta-regioselectivity of aryl ureas were found to depend on the aromaticity of the corresponding aryl substituents. Thus, aromaticity is a new factor which can affect the regioselectivity
