Abstract

Abstract Aromatic aldehydes are reductively dimerised by Me 3 Si Hg SiMe 3 (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 O, O-bissilyl products (1, 6- ...
