Preparation and chemistry of an unexpectedly stable α-oxoketene-pyridine zwitterion, 2,2-bis(tert-butylcarbonyl)-1-[4-(dimethylamino)pyridinio]ethen-1-olate

Treatment of dipivaloylketene 1 and its dimers 2 and 3 with 4-(dimethylamino)pyridine (DMAP) in acetonitrile affords the α-oxoketene-pyridine zwitterion 4 as a pale yellow solid. This is the first example of a stable zwitterion obtained from a true α-oxok
