资源简介:
2,4,6-Tri-tert-butyl-1,3,5-triphosphabenzene forms η1 complexes with [AuL]+. Significant structural differences are observed between the P3(CtBu)3 units, depending on the auxiliary ligand bound to gold. For L = NHC, a planar P3(CtBu)3 is observed; for L = P(tBu)2(o-biphenyl), the P3(CtBu)3 ligand is significantly puckered in the solid state. NICS computations on model complexes suggest this puckering only has a minor effect on the aromaticity of the heterocyclic ring.
