Abstract

Abstract The action of triethylsilane on α-ethylenic aldehydes has been studied in the presence of two types of nickel catalysts as well as palladium on charcoal. Two phenomena can result: either 1, 2 or 1, 4 additions only, the trans-1, 4 adduct being predominant, or a competition between these two additions and coupling reactions. A comparative regioselective and stereoselective study was carried out making use of, in addition to the ...
