- Abstract
Keywords: aromaticity; crystallography; density functional calculations; heterocycles; phosphinine EN aromaticity crystallography density functional calculations heterocycles phosphinine 12711 12711 1 09/08/21 20210906 NES 210906 B The very low basicity b and nucleophilicity of the phosphorus donor in phosphinines can be drastically increased by introducing strongly -donating Me SB 3 sb Si substituents to the aromatic phosphorus heterocycle. The highest gas-phase basicity was found for 2,3,5,6-tetrakis(trimethylsilyl)phosphinine, which is even more basic in the gas phase than pyridine.
