Ma. Ciriano et al., THE UNEXPECTED FORMAL INSERTION OF A CARBONYL GROUP INTO A HETEROCYCLIC N-IR BOND, Journal of organometallic chemistry, 469(2), 1994, pp. 30000031-30000033
Reaction of the dioxygen complex [Ir(C7H4NS2)(O2)(CO)(PPh3)2] (C7H4NS2
= benzothiazole-2-thiolate) with SO2 produces the unprecedented incor
poration of the carbonyl group into the benzothiazole-2-thiolate ligan
d through the heterocyclic nitrogen, in addition to the oxidation to s
ulfate, yielding [Ir{C(O)NC(S)SC6H4}(SO4)-(PPh3)2].
