The synthesis and characterization of new water-soluble platinum(0) complexes bearing sulfonated N-heterocyclic carbene (NHC) and divinyltetramethylsiloxane (dvtms) ligands are described. These complexes, of the general formula (NHC)Pt(dvtms), are active and recyclable catalysts for the hydrosilylation of phenylacetylene and other alkynes at room temperature in water. Our findings indicate that the
描述了带有磺化N-杂环卡宾(NHC)和二乙烯基四甲基硅氧烷(dvtms)配体的新型水溶性铂(0)配合物的合成和表征。这些具有通式(NHC)Pt(dvtms)的配合物是在室温下在水中将苯乙炔和其他炔烃氢化硅烷化的活性和可循环使用的催化剂。我们的发现表明,尽管在纯水中高于80°C的温度下观察到水解,但在这些催化条件下NHC–Pt(0)键仍相当稳定。
