Abstract 31 P NMR spectroscopy is a consolidated tool for the characterization of organophosphorus compounds and, more recently, reaction monitoring. The evolution organic synthesis, mainly due to combination elaborated building blocks with enabling technologies, generated great challenges understand and optimize synthetic methodologies. In this sense, experiments also became routine technique monitoring, accessing products side yields, chiral recognition, kinetic data, intermediates, as well basic parameters, such acid‐base hydrogen‐bonding. This review deals these aspects demonstrating essential role spectroscopy. recent publications (the last ten years) will be explored, discussing strategies accomplished detect and/or quantify distinct molecules, approaching mechanism, stability, stereochemistry, utility probe.

Abstract A regioselective, operationally simple and scalable protocol was developed for the synthesis of 9,10‐bis(organochalcogenyl)phenanthrenes seleno‐spiro[cyclohexane‐1,1′‐indene]‐2,5‐dien‐4‐ones through cyclization (biphenyl‐2‐alkyne)chalcogenides. The reaction occurs in presence diorganyl diselenides, Oxone® as a green oxidizing agent, acetonitrile at 80 °C. In this study, 20 compounds were obtained yields up to 97 % short times (1–4 h).
