Abstract :
3-(Trialkylsilyl)- and 3-(trialkylgermyl)-2-propynals as well as 2-propynal react with secondary phosphine oxides by carbonyl group under mild conditions (−10 to 22 °C) to give corresponding tertiary phosphine oxides with acetylenic and hydroxyl moieties in quantitative yield. The reactivity of the aldehydes in this reaction drops in the following order: HCCC(O)H>Me3SiCCC(O)H>Et3GeCCC(O)H.
