Titanocene-η–alkyne complexes such as 1 are efficient catalysts for the hydroamination of terminal alkynes to imines (see scheme; R=alkyl, R′=SiMe3 or Ph). Excellent yields of imines and good to excellent regioselectivities for the anti-Markovnikov products were obtained.
Tillack et al. (Mon,) studied this question.
