“…The importance of silicones have impacted our modern lives immensely, which is why silicon chemistry is at the highest level of interest. Current research in polysiloxanes is directed, among other things, towards simple and green synthetic strategies and proceedings in this area were recently highlighted [9] …”

Siloxanes have evolved into a multi‐million dollar business due to their manifold of commercial and industrial applications. As siloxanes have high hydrophobicity, low basicity, high flexibility and also high chemical inertness in common, their chemistry differs significantly from that of organic ethers. The discovery of organic crown ethers, for instance, is commonly accepted as the birth of synthetic host‐guest chemistry. Regarding the chemical properties of siloxanes, cyclic siloxanes which formally resemble silicon analogues of crown ethers, have received considerably less interest in terms of their host‐guest chemistry. Hence, only little is known about siloxane coordination chemistry in the chemical community and the number of published works in this field has been very low till lately. In the last few years, the field has significantly advanced and elegant methods were established to enable the Si−O−Si unit for coordination. This review therefore summarizes the recent developments in the field, recapitulates the historical aspects of siloxane coordination chemistry and describes the specific Si−O bond character with regard to different siloxane linkages. Implications on Si−O bond activation are included and the limits of siloxane coordination are redefined.

“…With the obvious exception of polydimethylsiloxane (PDMS), all synthetic polymers in widespread clinical use and indeed the vast majority in the research literature utilize organic polymers. However, incorporating main group elements into macromolecules can lead to unique properties that are unachievable with carbon and as such are of increasing interest as carbon-based polymers are pushed to their limits [3]. Phosphorus, being one of the most synthetically versatile and multifaceted elements, comprises a vast number of classes of compounds and is widely applied in fields as far reaching as pharmaceutical to flame retardants and from food additives to pesticides.…”

Main-Chain Phosphorus-Containing Polymers for Therapeutic Applications

Polymers in which phosphorus is an integral part of the main chain, including polyphosphazenes and polyphosphoesters, have been widely investigated in recent years for their potential in a number of therapeutic applications. Phosphorus, as the central feature of these polymers, endears the chemical functionalization, and in some cases (bio)degradability, to facilitate their use in such therapeutic formulations. Recent advances in the synthetic polymer chemistry have allowed for controlled synthesis methods in order to prepare the complex macromolecular structures required, alongside the control and reproducibility desired for such medical applications. While the main polymer families described herein, polyphosphazenes and polyphosphoesters and their analogues, as well as phosphorus-based dendrimers, have hitherto predominantly been investigated in isolation from one another, this review aims to highlight and bring together some of this research. In doing so, the focus is placed on the essential, and often mutual, design features and structure–property relationships that allow the preparation of such functional materials. The first part of the review details the relevant features of phosphorus-containing polymers in respect to their use in therapeutic applications, while the second part highlights some recent and innovative applications, offering insights into the most state-of-the-art research on phosphorus-based polymers in a therapeutic context.

Palladium‐Catalyzed Stereoselective Intramolecular Heck Dearomative Silylation of Indoles

et al. 2022

A palladium‐catalyzed stereoselective intramolecular Heck dearomative of indoles with silyl termination has been developed. A type of tetracyclic indoline derivatives containing silicon were prepared, involving N‐(2‐bromobenzoyl)indoles and silylboronates. This protocol not only led to a broad substrate scope in acceptable yields but also could be scaled up to gram quantities as well as further synthetic transformation.
