Reaction Conditions:

with copper(l) iodide;C₃₁H₂₆N₄PPdS⁽¹⁺⁾*Cl^(1-);sodium hydroxide in ethanol;toluene at 110; for 14 h;Catalytic behavior;Sonogashira Cross-Coupling;

Steps:

2.5.3. General procedure for Sonogashira coupling reactions
General procedure: To slurry of aryl halide (1 mmol), cuprous iodide (10 mol%) andpalladium catalyst (a known mol%) in an appropriate solvent(4 mL), phenylacetylene (1.2 mmol) and NaOH (1.7 mmol) wasadded and heated at required temp. After completion of the reaction(monitored by TLC), the flask was removed from the oil bathand water (20 mL) added, followed by extraction with ether(4 10 mL). The combined organic layers were washed with water(3 10 mL), dried over anhydrous Na2SO4, and filtered. Solventwas removed under vacuum. The residue was dissolved in hexaneand analyzed by GC-MS using Elite-5 columns, which are fused silicacapillary columns coated with 5% diphenyl and 95% dimethylpolysiloxane.
