Using silyl-molybdenum complexes in conjunction with DMF (Me₂NCHO), dihydroorganosilanes (R¹R²SiH₂) can be converted catalytically to polysiloxanes (-(R¹R²SiO)_n-). In the reactions, DMF plays a dual role of a solvent and more importantly as the oxygen source. The addition of fluoride compounds (TBAF ((n-C₄H₉)₄NF) or KF) as a cocatalyst has been found to enhance the molecular weight of the resulting polysiloxanes. Since the reactions proceed under mild conditions, a variety of dihydroorganosilanes bearing sensitive functional groups such as amino, methoxycarbonyl, perfluorophenyl, and ferrocenylalkyl were amenable to our protocol. In addition, (-)-mentylmethylsilane gave an optically active polysiloxane. This optical activity might be due to the prevailing helicity of the main chain. Furthermore, the catalytic polymerization of a prochiral monomer (cyclo-C₆H₁₁SiMeH₂) using a chiral molybdenum complex derived from [MoH₄(dppe)₂] and (-)-menthylsilane afforded a polymer displaying optical activity. The present one-step procedure is an efficient method for synthesis of functional polysiloxanes that are highly modified.

使用甲硅烷基钼配合物与DMF（Me ₂ NCHO）结合，可以将二氢有机硅烷（R ¹ R ² SiH ₂）催化转化为聚硅氧烷（-（R ¹ R ² SiO）_n-）。在反应中，DMF起到溶剂的双重作用，更重要的是作为氧气源。氟化物的添加（TBAF（（n -C ₄ H ₉）₄已发现NF）或KF）作为助催化剂可提高所得聚硅氧烷的分子量。由于反应在温和的条件下进行，因此各种带有敏感官能团（如氨基，甲氧基羰基，全氟苯基和二茂铁基烷基）的二氢有机硅烷均适合我们的方案。另外，（-）-薄荷基甲基硅烷得到光学活性的聚硅氧烷。这种光学活性可能是由于主链的普遍螺旋度。此外，使用衍生自[MoH ₄（dppe）₂的手性钼配合物]催化前手性单体（环-C ₆ H ₁₁ SiMeH ₂）]和（-）-薄荷基硅烷提供显示出光学活性的聚合物。本一步程序是一种合成高度改性的功能性聚硅氧烷的有效方法。
