Aromatic aldehydes are reductively dimerised by Me3SiHgSiMe3 (I), yielding bis(O-silyl)hydrobenzoin derivatives. 1,2-Diketones undergo 1,4-addition with formation of bis(O-silyl)enediols, while esters of conjugated dicarboxylic acids give O-silyl ketene acetals: maleic yields mainly the C,O-bissilyl derivative (1,4-addition), whereas fumaric and ethylene tetracarboxylic esters yield mainly the corresponding
芳香醛是由我还原二聚3 SiHgSiMe 3(I),得到双(ø -甲硅烷基)氢化苯偶姻衍生物。1,2-二酮经过1,4-加成反应生成双(O-甲硅烷基)烯二醇,而共轭二羧酸的酯则生成O-甲硅烷基烯酮缩醛:马来酸主要产生C,O-双甲硅烷基衍生物(1,4- ,而富马酸酯和乙烯四羧酸酯主要产生相应的O,O-双甲硅烷基产物(1,6-加成)。1,2-和1,4-醌很容易被(I)转化成相应的双O-甲硅烷基)苯系。
