2,2-Di(ethoxy)vinyllithium: A synthetic equivalent of the ethyl acetate anion
Wei,Schlosser
, p. 2771 - 2772 (1996)
2,2-Diethoxyvinyllithium can be readily generated from 2-bromo-1,1,-diethoxyethylene by treatment with butyllithium. When dissolved in tetrahydrofuran, it can be stored at -25°C for hours, but decomposes rapidly at 0°C.

, p. 5507 - 5510 (2007/10/03)
2,2-Di(ethoxy)vinyllithium 2 generated from bromo ketene acetal 1 reacts with carbonyl compounds to give either β-hydroxy esters 5 or conjugated esters 6 or hydroxy ketene acetals 7 according to the work up.
