Participants

Reaction Steps

235 g of the propenal from Example 71 (1.48 moles) were hydrogenated on a Parr shaker with 2.5 g of 5% Pd on carbon. The resulting propanal, 231.8 g, was distilled to afford 221.7 g of purified product (96% yield). BP 59° C./5 mmHg; 1H-NMR (300 MHz), spectra consistent with assigned structures; 13C-NMR (75 MHz), spectra consistent with assigned structures; IR (Neat), 2980, 2700, 1730, 1480, 1370; MS (m/e), 141 (M+ -15), 123, 98, 83, 57 (Base);
