Keten. Part VI. The adducts of dimethylketen with diarylnitrones
Abstract
Dimethylketen reacts with CN-diphenylnitrone to form the 1 : 1- and 2 : 1-adducts 2-(2-benzylideneiminophenyl)-2-methylpropanoic acid (IXa) and α(3,3-dimethyl-2-oxoindol-1-yl)benzyl isobutyrate (IIIa), respectively. Similar adducts are formed from C-phenyl-N-(o-tolyl)nitrone.
