Reactions of substituted arynes and diphenylphosphine oxide or diphenylphosphine-borane complex toward dibenzophospholes – impact of aryne substituents
Résumé
The reaction of diphenylphosphine oxide successively with two aryne precursors was investigated in order to access valuable functionalizable non-symmetrical dibenzophospholes. The reactions proved sensitive to substituents of aryne precursors able to coordinate the incoming lithiated nucleophile.
