Abstract
Transition-metal-catalyzed sila-cycloaddition has been a promising tool for accessing silacarbocycle derivatives, but the approach has been limited to a selection of well-defined sila-synthons. Herein, we demonstrate the potential of chlorosilanes, which are industrial feedstock chemicals, for this type of reaction under reductive nickel catalysis. This work extends the scope of reductive coupling from carbocycle to silacarbocycle synthesis and from single C-Si bond formation to sila-cycloaddition reactions. The reaction proceeds under mild conditions and shows good substrate scope and functionality tolerance, and it offers new access to silacyclopent-3-enes and spiro silacarbocycles. The optical properties of several spiro dithienosiloles as well as structural variations of the products are demonstrated.

Abstract
Fluorescent dyes such as rhodamines are widely used to assay the activity and image the location of otherwise invisible molecules. Si-rhodamines, in which the bridging oxygen of rhodamines is replaced with a dimethyl silyl group, are increasingly the dye scaffold of choice for biological applications, as fluorescence is shifted into the near-infrared while maintaining high brightness. Despite intense interest in Si-rhodamines, there has been no exploration of the scope of silicon functionalization in these dyes, a potential site of modification that does not exist in conventional rhodamines. Here we report a broad range of silyl modifications that enable brighter dyes, further red-shifting, new ways to modulate fluorescence, and the introduction of handles for dye attachment, including fluorogenic labeling agents for nuclear DNA, SNAP-tag and HaloTag labeling. Modifications to the bridging silicon are therefore of broad utility to improve and expand the applications of all Si-dyes. Functionalization of the bridging silicon atom of Si-rhodamine dyes allows tuning of dye performance, the attachment of sensors, and the addition of biomolecular targeting ligands useful for the construction of live cell imaging probes.![]()
