Reaction Conditions:
with water;di[triaqua{2,6-di(phenylthiomethyl)pyridine}ruthenium(III)] tri-sulphate; pH=2.0 at 80; for 12 h;Product distribution / selectivity;
Steps:
7
[Example 7]; 0.1 mmol of water-soluble acetylene carboxylic acids whose R1 is COOH and R2 is H in Fig. 1 (a) was mixed with 2 mL of aqueous solution containing 3.1 mg (2.5 μmol) of di[triaqua {2,6-di(phenylthiomethyl)pyridine} ruthenium (III)] 3-sulphate, and the mixture was reacted at the pH 2.0 at 80°C under argon atmosphere for 12 hours. The resulting mixture was condensed to give a product. The product was analyzed by 1H NMR.
