WebMay 11, 2006 · A theoretical analysis of four molecules (phosphole, phospholane, pyrrole, and pyrrolidine) in their ground and transition states has been carried out. The transition state of phosphole is highly aromatic and a partition of its energy into atomic contributions reveals that it is the phosphorus atom that is responsible for this observation. WebSince phospholanes are well known to polymerize in the presence of Lewis acids, an alternative mechanism that does not rely on quantitative oxidation of the phospholane …
