Popis:	Treatment of acetaldehyde N-ter-butylimine by two equivalents of LDA, followed by trimethylsilyl chloride trapping affords the α,α-disilylated imine ; the latter reacts with aromatic aldehydes producing α,β-ethylenic aldehydes in excellent yields and with very high stereoselectivity in favour of the E isomer.
