Dialkoxytitanacyclopropanes and dialkoxytitanacyclopropenes react with one molecule of carbon dioxide to afford diversely substituted carboxylic acids after hydrolysis.
Titanium-mediated carboxylation of alkynes with carbon dioxide
Six, Yvan
, p. 1157 - 1171 (2007/10/03)
The regioselective carboxylation of nonactivated internal alkynes can be performed with carbon dioxide under atmospheric pressure using a simple procedure based on the chemistry of Sato-type diisopropyloxytitanacyclopropenes. Various polysubstituted vinylcarboxylic acids and butenolides can be prepared in this way. In addition, this paper describes an experimental protocol for the preparation of solutions of (η2-cyclopentene)diisopropyloxytitanium. This complex also reacts with carbon dioxide, and mediates pinacol coupling of acetophenone. Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2003.
