HAMMETT-CORRELATIONS, SOLVENT EFFECTS AND STEREOCHEMISTRY OF THE THERMAL DECARBOXYLATION OF 2-OXETANONES - EVIDENCE FOR A ZWITTERIONIC INTERMEDIATE
Mulzer, Johann.,Zippel, Matthias
, p. 751 - 754 (1980)
Kinetic and stereochemical data of the thermal decarboxylation of 2-oxetanones (1 and 2) indicate that the reaction proceeds via a zwitterionic intermediate Z.
Cp2TiCl2-catalyzed hydrocarboxylation of alkynes with CO2: formation of α,β-unsaturated carboxylic acids

Cp2TiCl2-catalyzed hydrocarboxylation of alkynes with CO2 (atmospheric pressure) has been reported. A range of alkynes were transformed to the corresponding α,β-unsaturated carboxylic acids in high yields with high regioselectivity. The reaction proceeded with hydrotitanation, transmetalation, and subsequently carboxylation with CO2
