leads to formation of corresponding thiophene-1,1,1'1'-tetroxides ( 2a-d ). Nucleophilic addition of secondary amines to thiophene-1,1,1'1'-tetroxides ( 2a-d ) has been studied. It has been shown that the basicity of amine and the nature of solvent determine the reaction pathway. In water, the addition of two dimethylamine or piperidine molecules and only one diethylamine or morpholine molecule to
在有机溶剂(苯、THF)中,观察到两个哌啶分子添加到双[2-(5-三甲基甲硅烷基)噻吩基]二甲基硅烷的每个噻吩-1,1-二氧化物片段中。在这种情况下,三甲基甲硅烷基和二甲基甲硅烷基都发生了脱甲硅烷基化。
