Transformation of sulfur dioxide to sulfate at a palladium centre
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
