Thus, the reaction between [Ru₃(CO)₁₀(μ-dppm)] and sacH in refluxing benzene leads to the formation of [Ru₃(CO)₈(μ-dppm)(μ-H)(μ-sac)] (<strong>1</strong>) and [Ru₂(CO)₄(μ-dppm)(μ-sac)₂] (<strong>2</strong>), with the triruthenium <strong>1</strong> being isolated as the major product. The sac ligand displays the typical edge-bridging coordination mode using nitrogen and the amide oxygen atoms in both <strong>1</strong> and <strong>2</strong>. Oxidative decarbonylation of <strong>1</strong> using Me₃NO in the presence of PPh₃ affords simple phosphine-substituted product, [Ru₃(CO)₇(μ-dppm)(μ-H)(PPh₃)(μ-sac)] (<strong>3</strong>), at room temperature which converts into [Ru₃(CO)₄(μ-H)(μ₃-H)(η¹-Ph)(μ-PPh₂){μ-Ph₂PCH₂P(Ph)C₆H₄}(μ₃-sac)] (<strong>4</strong>) upon thermolysis in refluxing toluene. The coordination mode of the sac ligand changes from edge-bridging to triply-bridging/face-capping during the conversion process. The triply-bridging coordination mode of the sac ligand observed in <strong>4</strong>, where it bridges a metal-metal edge using the nitrogen atom and coordinates with a third metal atom through the amide oxygen atom, is novel. Compound <strong>2</strong> also reacts with PR₃ (R = Ph, OMe) at room temperature to yield simple phosphine-substituted product, [Ru₂(CO)₃(μ-dppm)(PR₃)(μ-sac)₂] (<strong>5</strong>, R = Ph; <strong>6</strong>, R = OMe), however, “flipping” of one of the coordinated sac ligand is also observed during this substitution reaction.

Conventional strategies, including nucleophilic substitution, electrophilic selenation, and transition-metal–catalyzed cross-coupling, though powerful, typically require prefunctionalized substrates, multiple steps, and generate undesirable waste. In the last decade, direct C–H selenation has emerged as a modern and transformative approach that enables the direct conversion of inert C–H bonds into C–Se bonds without preactivation. This strategy embodies step and atom economy, provides access to structurally diverse selenium-containing frameworks, and offers unique opportunities for late-stage functionalization of bioactive molecules and complex scaffolds. Advances in transition-metal catalysis, photocatalysis, and electrochemical activation have expanded the scope of C–H selenation to arenes, heteroarenes, alkenes, and even alkanes under increasingly mild and sustainable conditions.
