The synthesis and ruthenium-catalyzed hydrosilylation reactions of 3-dimethylsilyl-2-ethynylpyridine derivatives (1a-1d) were described. Pyridine-fused siloles (2a and 2b) were obtained through intramolecular hydrosilylation of 1a and 1b in the presence of a ruthenium catalyst. The UV-Vis absorption and fluorescence properties of 2a and 2b were studied, and DFT calculations were performed to understand their photophysical properties.

The reaction of 1a and 1b in the presence of a ruthenium catalyst gave the corresponding pyridine-fused siloles (2a and 2b) through intramolecular hydrosilylation. The UV-Vis absorption and fluorescence properties of 2a and 2b were investigated, and DFT calculations were performed to understand their photophysical properties.
