Abstract

A series of symmetric and unsymmetric N, N-bis (diarylphosphino) amine ('PNP') ligands (Ar2PN (R) PNAr′ 2: R= Me, Ar2= o-anisyl, Ar′ 2= Ph, 1, R= Me, Ar2= o-tolyl, Ar′ 2= Ph, 2, R= Me, Ar2= Ph (o-ethyl), Ar′ 2= Ph, 3, R= Me, Ar2= Ar′ 2= o-anisyl, 4, R= iPr, Ar2= Ar′ 2= Ph, 5) and symmetric N, N′-bis (diarylphosphino) dimethylhydrazine ('PNNP') ligands (Ar2PN (Me) N (Me) PAr2: Ar2= o-tolyl, 6, Ar2= o-anisyl, 7) have been synthesised ...
