摘要

Abstract: Pyramidal inversion barriers (AG*) of variously substituted phospholes, a phosphindole, and a dibenzophosphole have been measured and compared with the inversion barriers of model compounds. It has been found that alkyl or aryl substituents do not significantly influence the unusually low barrier to pyramidal inversion (ca. 15-16 kcal/mol) at phosphorus in the phosphole system, but that mono-and diannulation (with a ...
