将甲烷直接转化为CH3Cl的现有技术方法在腐蚀性条件下运行，并且通常产生需要随后分离的氯甲烷混合物。我们报告了一种机械化学策略，选择性地将甲烷转化为氯甲烷在整体良性条件下，采用三氯异氰尿酸（TCCA）作为一种廉价和无腐蚀性的固体氯化剂。TCCA被证明在与刘易斯酸如氧化铝和二氧化铈研磨以在中等温度下官能化甲烷时释放活性氯物质（
State-of-the-art processes to directly convert methane into CH3Cl are run under corrosive conditions and typically yield a mixture of chloromethanes requiring subsequent separation. We report a mechanochemical strategy to selectively convert methane to chloromethane under overall benign conditions, employing trichloroisocyanuric acid (TCCA) as a cheap and noncorrosive solid chlorinating agent. TCCA is shown to release active chlorine species upon milling with Lewis acids such as alumina and ceria to functionalize methane at moderate temperatures (
