M. Sanchez et al., INTRAMOLECULAR DONOR-STABILIZED PHOSPHANYLIUM SALTS VIA LAMBDA(3)-FUNCTIONALIZED-IMINOPHOSPHANES, Tetrahedron letters, 36(12), 1995, pp. 2085-2088
nes,R-P=NAr(Ar*=2,4,6-tri-tBuC(6)H(2)),containing intramolecularly co
ordinating 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.
