Hydration of Alkynes by a PtCl4−CO Catalyst

Autor: Jochanan Blum, Waël Baidossi, Michal Lahav

Publikováno v: The Journal of Organic Chemistry. 62:669-672

Treatment of PtCl(4) with CO at 40-110 degrees C forms a powerful alkyne hydration catalyst that operates both under homogeneous conditions in wet THF and under phase-transfer conditions in (CHCl(2))(2)/H(2)O in the presence of tricaprylmethylammoniu
