Tuning the electronic effects of aromatic phosphorus heterocycles:An unprecedented phosphinine with significant P(π)-donor properties

\u3cp\u3eA hitherto unprecedented electronic situation has been observed for a substituted, pyridyl-functionalized phosphinine. In contrast to previous studies, this compound shows considerable π-donor properties as the result of the rather strong +M effect of the CH\u3csub\u3e3\u3c/sub\u3eS-substituent, changing the electronic properties of this low-coordinate and aromatic phosphorus heterocycle substantially.

Recent developments in the chemistry of pyridyl-functionalized, low-coordinate phosphorus heterocycles

\u3cp\u3eThis highlight review provides an overview of recent developments in the chemistry of pyridyl-functionalized λ\u3csup\u3e3\u3c/sup\u3eσ\u3csup\u3e2\u3c/sup\u3e-phosphinines and 3H-1,2,3,4-triazaphospholes. The access to novel chelating, low-coordinate phosphorus heterocycles can lead to a much broader scope for potential applications. New developments in areas such as homogeneous catalysis, molecular materials, and supramolecular chemistry can consequently be foreseen in the near future.\u3c/p\u3
