Phenylacetylene → HCID 178506790, compound

Participants

Reaction Steps

A solution of fresh LiC≡CPh was prepared by reacting 0.118 mL of phenylacetylene (1.08 mmol) and 0.48 mL of 1.5M hexane nBuLi solution (0.72 mmol) in 50 mL of dry THF at −78° C. for 0.5 hour. The solution was added drop wise via cannula to a solution of 150 mg of Ir(ppy)2(MeOH)2OTf (0.18 mmol) in 10 mL of dry THF at −78° C. The mixture was reacted for 1 h at −78° C. and the temperature was raised to RT over 2 hours. The solvent was removed under reduced pressure obtaining the Ir(ppy)2(CCPh)2Li.
