WebNov 6, 2024 · The extension of the π-plane of phosphole oxides is known to be beneficial for π–π stacking and electron-spin delocalization, and may tune the electron affinity of the π-systems. The presence of a triazole moiety should result in an extended π-plane to bring about some beneficial effects. WebBenzophosphole. Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). Benzophosphole is the organic compound with the chemical formula C 8 H 7 P; it is the phosphorus analog of indole. [2] The term benzophosphole also refers to substituted derivatives of the parent heterocycle . WebThe oxygen atom is attached to the β carbon atom of the phosphole exclusively. The C C bond in the product cannot react with the nitrone. This work demonstrates that slightly antiaromatic phosphole sulfides are capable of acting as 2π-electron components in cycloaddition reactions. canadian heating products langley bc
