  摘要：

  The 2-trimethylsilyl-2,3-butadienal is easily prepared, in good yield, by the reaction at -80-degrees-C between triethylorthoformate and the organoaluminum compound prepared from Me3SiC=C-CH2Br. The resulting conjugated aldehyde reacts readily with various organometallic compounds (containing Al, Mg, Zn) to produce alcohols resulting from an 1,2-addition only, but for the saturated or phenylic magnesium derivatives which also give products from 1,4-addition.
