Abstract

Reaction of 4,4′,4″-tri(tert-butyl)-2,2′:6′,2″-terpyridine (terpy*) with gaseous SO2–O2 mixtures and [PdCl2(MeCN)2] followed by aqueous workup affords crystallographically characterised [PdCl(terpy*)]Cl and both O- and S-bound [Pd(SO3)(terpy*)]. The former is also available from [PdCl2(MeCN)n] (n = 0, 2) and terpy*; the latter from aerobic oxidation of [Pd(dba)2]–terpy*–SO2 mixtures (dba = dibenzylideneacetone). Oxidation of [Pd(SO3)(terpy*)] with O2 (at 210 °C in PhNO2) yields crystallographically characterised O-bound [Pd(SO4)(terpy*)]. The crystal structures of two related compounds are also reported: [Pd(OAc)(terpy*)]Cl and [PdCl2(bipy*)].
