A systematic study on the use of silanols and phenols as effective activators in Mo(CO)₆ – based catalytic systems for metathesis of 4-decyne and 1-phenyl-1-propyne is reported. In comparison with traditionally used phenols, aryl-substituted silanols exhibit high activating potential of molybdenum species even at lower concentrations (2 mol% of Mo(CO)₆ and 4–20 mol% of silanol depending on the alkyne) at toluene reflux. Silylated phenols and silanols are also suitable as co-catalysts. Additionally, Mo(CO)₆/silanol catalytic system is shown to be efficiently activated by UV-irradiation at room temperature, whereas it is less effective for metathesis reactions performed in the presence of phenols.

有系统地研究了在基于Mo（CO）3的催化体系中使用硅烷醇和苯酚作为有效活化剂进行4-癸炔和1-苯基-1-丙炔复分解的研究。与传统使用的苯酚相比，芳基取代的硅烷醇即使在甲苯回流下浓度较低时（钼（CO）3为2 mol％，而炔烃为4-20 mol％）也具有较高的钼活化活性。甲硅烷基化的酚和硅烷醇也适合作为助催化剂。另外，Mo（CO）3 /硅烷醇催化体系显示出在室温下被紫外线辐射有效地活化，而对于在苯酚存在下进行的复分解反应则不太有效。
