Abstract
In this report, we describe the catalytic activation of terminal alkynes using TpRuPPh3(MeCN)2X (X = PF6 and SbF6) complexes. These ruthenium species enable transformation of terminal alkynes into π-alkyne, vinylidene, and allenylidene intermediates, and provide new catalytic reactions via three different pathways. Due to the cationic nature and the coordinative unsaturation around the ruthenium center, we observed the formation and scission of new types of C-X (X = O, N, C) bonds occurring in the catalytic transformations of terminal alkynes, as well as structurally reorganized products. This review summarizes some important examples.
