We report an efficient alkynylation reaction of aryl iodides with simultaneous ortho-alkylaton of aryl rings. The reaction between three simple reagents—aryl halides, alkynes, and alkyl halides—formed aryl–alkynyl bonds carrying hindered aryl rings in one step. The reaction proceeded via a Catellani...
