Abstract The synthesis of the phosphorus‐capped heptaphenylsilsesquioxane T 7 Ph P is reported. We show that, unlike previous examples, it readily forms Lewis acid‐base adducts with boranes different steric demand and FeCO 4 fragment. All complexes were characterized by multinuclear NMR IR spectroscopy in solution solid state. molecular structures BPh 3 B(C 6 F 5 ) determined from XRD suitable single crystals. relative conformation C rings P−B(C suggests favorable π‐interactions, stabilizing to such a degree that attempts activate H 2 or CO unsuccessful.

Abstract The present review covers various advances in the field of metal‐catalyzed coupling N ‐tosylhydrazones with compounds containing C−H/heteroatom‐H bonds, including transition metal catalysts i. e., Pd, Rh, Cu, Ag, Ni and Co resulting alkylated, alkenylated, alkynylated, allenylated, annulated many other products. A carbene migratory insertion process play a key role carbon‐carbon single bond (C−C) double (C=C) formation undergoes variety cascade reactions to synthesize wide scope pharmaceutically medicinally valuable scaffoldings.

Abstract Using organic dyes as photocatalysts is an innovative approach to photocatalytic transformations. These offer advantages such widespread availability, adaptable absorption properties, and diverse chemical structures. Recent progress has led the development of that can utilize visible light modify chemically inert C−H bonds. catalysts are sustainable, selective, versatile, enabling mild reactions, late‐stage functionalization, various transformations in line with green chemistry principles. As photoredox chemistry, they contribute efficient environmentally friendly synthetic pathways. Acridinium‐based have proved valuable transformative reactions under conditions. This review emphasizes their features, frameworks, applications modifying complex molecules. It provides overview recent advancements use acridinium‐based for bond functionalization without need transition metals, showcasing potential expedite new molecules igniting excitement about prospects this research field.
