Highly active in situ catalysts for anti-Markovnikov hydration of terminal alkynes.

Org. Lett. 8 , 5853, (2006)

The anti-Markovnikov hydration of terminal alkynes to give aldehydes is catalyzed by complexes derived in situ from air-stable [CpRu(eta6-naphthalene)]PF6 (C) and 6-aryl-2-diphenylphosphinopyridines (...
