Abstract: Engaging allenes in transition-metal-catalyzed C-H bond activation strategy is immensely promising to access high-value scaffolds. However, such a reaction manifold remains largely elusive using cheap and sustainable ruthenium catalysis. We disclose an unprecedented ruthenium-catalyzed (4… read more here.

Abstract: A novel potassium persulfate (K2S2O8) mediated thiolation of allenylphosphine oxides with diaryl sulfides is disclosed. Mechanistic studies indicate that K2S2O8 homolyzes the diaryl sulfide to produce a thiyl radical (PhS•), which is followed by C–O… read more here.
