研究了刘易斯酸对硝基甲烷酸式的活化作用。在硝基甲烷溶剂中，催化量的AuCl（3）或Cu（OTf）（2）存在下，1，3-二羰基化合物可以转化为亚甲基桥连的双-1，3-二羰基化合物。
Activation of the aci-form of nitromethane using Lewis acids for the attack of carbon nucleophiles was studied. 1,3-Dicarbonyl compounds in the presence of catalytic amounts of AuCl(3) or Cu(OTf)(2) in nitromethane solvent could be converted into methylene-bridged bis-1,3-dicarbonyl compounds.
