Intramolecular donor-stabilized phosphanylium salts via λ3-Functionalized-iminophosphanes

Abstract λ 3 -Iminophosphanes, R-P=NAr ∗ ( Ar ∗ =2,4,6-tri-tBuC 6 H 2 ),containing intramolecularly coordinating substituents at the dicoordinate phosphorus atom (R=8-NMe 2 C 10 H 6 or 2-Ph 2 PCH 2 C 6 H 4 have been synthesized and used for generation of the isolable phosphanylium salts stabilized by a donor P→ P bond.
