Palladium-catalyzed cross-coupling reactions of (benzoyloxymethyl)zinc iodide with diverse (het)aryl halides leading to (benzoyloxymethyl)(het)arenes were studied to define the scope of this reaction. It has been found that this reaction is only applicable for electron-deficient aryl halides and the most efficient it is for 2-halopyridines and 4-halopyrimidines. Deprotection of the intermediates gives
研究了钯催化的(苯甲酰氧基甲基)碘化锌与多种(杂)芳基卤化物产生(苯甲酰氧基甲基)(杂)芳烃的交叉偶联反应,以确定该反应的范围。已发现该反应仅适用于缺电子的芳基卤化物,并且最有效的是用于 2-卤代吡啶和 4-卤代嘧啶。中间体的脱保护以高产率得到(羟甲基)吡啶和-嘧啶。
