摘要

Treatment of PtCl4 with CO at 40-110° C forms a powerful alkyne hydration catalyst that operates both under homogeneous conditions in wet THF and under phase-transfer conditions in (CHCl2) 2/H2O in the presence of tricaprylmethylammonium chloride (Aliquat 336). Complex HPtCl (CO) 2 is regarded as the active hydration catalyst. It is assumed to be formed by initial transformation of PtCl4 to H2 [Pt3 (CO) 6] n (n= 5, 6) followed by reaction ...
