Abstract
Ammonium salts containing alongside 3-methyl-3-ethoxycarbonylbutanon-2-yl also 2-alkenyl or benzyl groups under the treatment with Na2CO3·10H2O afford products resulting from Stevens rearrangement. In the mentioned salts the ketoester group on treatment with sodium ethylate suspension in ether or benzene suffers partial or total acid cleavage, and then the Stevens 3,2-rearrangement takes place.
