چکیده
|
The hydroxypivaldehyde (hpa) precursor intermediate for the synthesis of neopentyl glycol (npg) is prepared by novel cross aldol condensation of isobutyraldehyde and formaldehyde at 20 °c using benzyltrimethylammonium hydroxide,a basic phase transfer catalyst. a feed mole ratio of 1.1:1.0:0.04 (isobutyraldehyde:formaldehyde:benzyltrimethylammonium hydroxide) afforded hydroxypivaldehyde as white solid in almost quantitative yield with ∼100% selectivity.[formula omited] © 2013
