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
