Abstract
It has been nearly 70 years since the discovery of Lindlar catalyst and its valuable ability to semi-hydrogenate alkynes to cis olefins. The Lindlar catalyst semi-hydrogenation mechanism appears to still be an ongoing discussion. Spectroscopy (NMR, MS) results are presented regarding the Lindlar catalyst semi-tritiation of terminal alkynes, providing evidence of a novel tritium for hydrogen exchange process taking place.
