Intramolecular Phosphinyl-Zincation of Alkynes: A Powerful Entry to Benzophosphole Oxides
{{output}}
Upon reacting ortho-alkynylated secondary arylphosphine oxides with Et2Zn, we discovered that P(O)─H activation is followed upon gentle heating by phosphinyl-zincation. This unprecedented transformation stands as a phosphorus version of the silyl and germyl-z... ...
