要旨:
Make mine a triple: The tetraphenyl phosphonium salts of [(CF3)3BCX]− (X=P, As) are stable even well above room temperature. The synthesis of these first phospha‐ and arsaethynyl complexes of boron from (CF3)3BCO is carried out in two steps (see scheme). The complex [(CF3)3BCAs]− is the first stable anionic arsaalkyne.
