A dramatic effect of aryloxo ligands on the titanium-catalyzed hydroamination of alkynes.

Vivek Khedkar1, Annegret Tillack, Matthias Beller.   

Abstract

The aryloxotitanium complex 1 is a highly chemo- and regioselective catalyst for intermolecular hydroamination of terminal alkynes. Branched imines are obtained in good to excellent yield (up to 99%) with various primary aromatic and aliphatic amines. [reaction: see text]
