Abstract
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 with HCl (generated by decomposition of the starting platinum salt).Keywords
