YieldReaction ConditionsOperation in experiment
83% In ethanol; chloroform; at 20℃; for 3h; 2.3 [PdCl(sac)(kappa2-dppf)] (2) A warm ethanol (10 cm3) solution of sodium saccharinate (0.112 g, 0.55 mmol) was added to a chloroform (20 cm3) solution of [PdCl2(kappa2-dppf)] (0.20 g, 0.27 mmol). Following a similar procedure to above, [PdCl(sac)(kappa2-dppf)] (2) was isolated as a red-brown crystalline solid in 83percent yield. 1H NMR: delta 8.31-7.01 (m, 24H, Ar), 4.32 (br, 4H, CH), 3.42 (br, 4H, CH); 31P{1H} NMR: delta 37.20 (d, JPP 12.7 Hz), 28.99 (d, JPP 12.7 Hz).

YieldReaction ConditionsOperation in experiment
96% In ethanol; at 50℃; for 4h; To the solution of CEE hydrochloride 22 (1 .0 mmol, 195 mg) in EtCH (15 mL)equimolar quantity of sweetener salt (potassium 6-methyl-4-oxo-4H-1 ,2,3-oxathiazin-3-ide2,2-dioxide 0.201 g for 20a and sodium benzo[d]isothiazol-3-olate 1,1-dioxide hydrate 0.205g for 20b) was added and the mixture was then stirred for 4h at the 50 C. Sodium or potassium chloride, formed during the reaction, was separated by filtration through the 22 micron membrane filter and the filtrate was taken to dryness. Diethyl ether was added to the products and after it was evaporated, products 23a and 23b were isolated as white solids in quantitative yields.
