Phosphole
WebAug 27, 2024 · Introduction. In sharp contrast to pyrrole, which is a planar and strongly aromatic heterocycle, its immediately heavier analogue, phosphole, is characterized by a highly pyramidalised arrangement of the substituents around the phosphorus and, as consequence, a severely diminished degree of aromaticity. 1 This geometry is adopted … WebMar 12, 2015 · We have prepared a range of alkynyl benzoates in high yields and have investigated their reactivities with the strong Lewis acid B(C6F5)3. In such molecules both σ-activation of the carbonyl and π-activation of the alkyne are possible. In contrast to the reactivity of propargyl esters with B(C6F5)3 which proceed via 1,2-addition of the ester …

The most important reason for the high aromaticity of the phosphole 18 is the pπ − pπ bonding interaction between the filled p-orbital of the P atom and the vacant p-orbital of the B atom. The effect of the B-P π-bonding is to enhance the planarity of ...
