On treatment of the ylide 1591 with HMDS-Na 486, the resulting sodium salt 1592 reacts with valeric aldehyde and subsequently with TCS 14 to give 1593, which eliminates trimethylsilanol 4 to give the ylide 1594. This ylide 1594 converts aldehydes such as butyraldehyde into dienes such as 1595 in up to 48% yield [9]. The ylide 1596 reacts with CO2 to give the ylide 1597 which, on heating to 110-120 °C, eliminates HMDSO 7 to give (oxovinyliden)phosphorane 1598 [10] (Scheme 10.3). [Pg.242]

Compared to propene, butenes show a lower solubility in water. Due to this the observed hydroformylation reaction rate of butene mixtures like raffinate-II (in general 40 % butene-1, 40 % butene-2, 20 % butane isomers) is significantly lower than that found for propene. However, a slight increase in the catalyst concentration is sufficient to achieve satisfying space-time yields for the pro-duction of valeric aldehydes. As a very selective catalyst the Rh/TPPTS- stem does not catalyze the hydroformylation of butene-2... [Pg.197]

Transformation to 2,4-dinitrophenylhydrazones combined with the chromatopolarographic technique has also been used recently ) for the separation and determination of aliphatic aldehydes (cf. p. 183). The mixture of 2,4-dinitrophenylhydrazones of propionic, butyric, and valeric aldehydes is separated on a rubber column with isooctane and 70 per cent dimethylformamide containing 0-2 M potassium chloride. If the current at —1-3 V is plotted as a function of the eluated volume, three separate elution peaks are obtained. [Pg.127]
