[11C]Formaldehyde revisited: considerable concurrent [11C]formic acid formation in the low-temperature conversion of.
The reduction of [11C]carbon dioxide with lithium aluminium hydride in diethyl ether at temperatures ranging from -56 degrees C to 19 degrees C was studied. In contrast to what others have reported, considerable amounts of [11C]formic acid were found at all studied temperatures.
