Yield: 48%
Reaction Conditions:
Stage #1:trifluoromethan with potassium tert-butylate;copper(l) chloride in N,N-dimethyl-formamide at 20;Inert atmosphere;
Stage #2:triphenylphosphine in N,N-dimethyl-formamideInert atmosphere;
Steps:
34
Example 34; To a 0.31 M solution of stabilized CuCF3 in DMF (2.5 mL; 0.78 mmol) was added a solution of PPh3 (617 mg; 2.35 mmol) in dry DMF (1 .5 mL). After stirring overnight the mixture was treated with ether (10 mL). The white precipitate of [(Ph3P)3Cu(CF3)] was separated by filtration, washed with ether (3 * 5 mL), and dried under vacuum. The yield was 347 mg (48%). NMR (CH2CI2, 25 °C): 31 P, δ = -0.6 ppm (br,s); 19F, δ = -25.4 ppm (s). Purity (19F with an internal standard): 97%.
