Abstract

Photoactivated catalysts for the hydrosilylation of alkenes with silanes offer temporal control in manufacturing processes that require silicone curing. We report the development of a range of air-stable Pt(II) (salicylaldimine)(phenylpyridyl), [Pt(sal)(ppy)], complexes as photoinitiated hydrosilylation catalysts. Some of these catalysts show appreciable latency in thermal catalysis and can also be rapidly (10 s) activated by a LED UV-light source (365 nm), to give systems that selectively couple trimethylvinylsilane and hexamethylsiloxymethylsilane to give the linear hydrosilylation product. Although an undetectable (by NMR spectroscopy) amount of precatalyst is converted to the active form under UV-irradiation in the timescale required to initiate hydrosilylation, clean and reliable kinetics can be measured for these systems that allow for a detailed mechanism to be developed for Pt(sal)(ppy)-based photoactivated hydrosilylation. The suggested mechanism is shown to have close parallels with, but also subtle differences from, those previously proposed for thermally-activated Karstedt-type Pt(0) systems.

摘要

用于烯烃与硅烷硅氢化反应的光活化催化剂，为需要硅氧烷固化的制造过程提供了时间控制。我们报道了一系列空气稳定的Pt(II)（水杨醛亚胺）（苯基吡啶基），即[Pt(sal)(ppy)]配合物作为光引发硅氢化反应催化剂的开发。其中一些催化剂在热催化中表现出明显的潜伏性，并且还可以被LED紫外光源（365 nm）快速（10秒）活化，从而得到能够选择性地将三甲基乙烯基硅烷和六甲基硅氧基甲基硅烷偶联以生成线性硅氢化产物的体系。尽管在引发硅氢化反应所需的时间尺度内，在紫外光照射下，无法检测到（通过核磁共振光谱）的预催化剂转化为活性形式的量，但可以测量这些体系的清晰可靠的动力学，这有助于为基于Pt(sal)(ppy)的光活化硅氢化反应开发详细的机理。所提出的机理与先前为热活化的卡斯泰德型Pt(0)体系所提出的机理有密切的相似之处，但也存在细微的差异。
