After the pale yellow solution had been stirred at −78 °C for 30 min, 0.93 g (5.4 mmol) of Phenylthiocopper(I) was added from a bent tube attached to the reaction flask. The suspension was warmed to −20 °C and stirred for 30 min, which gave a red brown solution of the cuprate. The solution was cooled to −78 °C for addition to the iodo enone.2Handling, Storage, and Precautions: best used immediately following its preparation. THF and ether need to be anhydrous (distill from sodium benzophenone). Air and moisture should be excluded." @default.
