Transition‐Metal‐Free C−H Silylation: An Emerging Strategy

Silicon‐containing molecules are of great interest with widespread applications in several research areas such as polymer chemistry, materials science, medicinal chemistry, and complex molecule synthesis. Transition‐metal‐free C−H silylation is an essential process because this process is useful in fabricating carbon‐silicon bonds which can be further transformed into a number of other compounds. Since transition‐metal‐catalyzed C−H bond silylation is a developed field, therefore this context only contains transition‐metal‐free pathways for transforming C−H bond to C−Si (Si=SiR3) bond. This review has been further categorized and subcategorized based on intermediates involved and catalysts used during this transformation. This synopsis summarizes recent developments in the area of silicon chemistry with a focus of innovative transition‐metal‐free catalytic silylation using different strategies such as free radical, base promoted, Brønsted acid, Lewis acid, and frustrated Lewis pair. This review summarizes recent developments in the area of silicon chemistry with a focus of innovative transition‐metal‐free catalytic silylation using different strategies.
