摘要

双层硅倍半氧烷的氢硅烷化是制备杂化材料,尤其是聚合物材料的一种有效方法。Karstedt 的催化剂 Pt(dvs) 因其商业可用性、高产率和良好的氢硅化选择性而被广泛用于此目的。尽管如此,乙烯基苯仍会产生多种氢硅烷化产物。本研究采用了一种涉及铱催化剂的方法,该催化剂对乙烯基苯和双硅烷封端双层硅倍半氧烷的反马尔科夫尼科夫氢硅化产物的选择性明显提高。获得更高纯度的氢硅烷化产物将有助于发展混合材料的基本结构-性能关系。

Hydrosilylation of double-decker silsesquioxanes is an efficient approach for preparing hybrid materials, especially polymeric materials. Karstedt’s catalyst, Pt(dvs), is widely used for this purpose due to its commercial availability, high yields, and good hydrosilylation selectivity. Despite this, vinylbenzenes have been shown to produce multiple hydrosilylated products. This study employs a method involving an iridium catalyst that was significantly more selective for the anti-Markovnikov hydrosilylation product with vinylbenzenes and bis-silane-capped double-decker silsesquioxanes. Obtaining higher purity of hydrosilylated products will allow for the development of the fundamental structure–property relationship of hybrid materials.

期刊介绍: Organometallics is the flagship journal of organometallic chemistry and records progress in one of the most active fields of science, bridging organic and inorganic chemistry. The journal publishes Articles, Communications, Reviews, and Tutorials (instructional overviews) that depict research on the synthesis, structure, bonding, chemical reactivity, and reaction mechanisms for a variety of applications, including catalyst design and catalytic processes; main-group, transition-metal, and lanthanide and actinide metal chemistry; synthetic aspects of polymer science and materials science; and bioorganometallic chemistry.
