Retraction: Isolation of stable non cyclic 1,2-disulfoxides. Revisiting the thermolysis of S-aryl sulfinimines

Abstract

Retraction of ‘Isolation of stable non cyclic 1,2-disulfoxides. Revisiting the thermolysis of S-aryl sulfinimines’ by José A. Souto et al., Chem. Commun., 2014, 50, 12630–12632, https://doi.org/10.1039/C4CC05751A.

We the authors, hereby wholly retract this ChemComm article. The conclusions in this work proposed the generation of Ar–S(O)–S(O)–Ar disulfoxides by thermolysis of S-aryl sulfinimines, identified by X-ray crystallography.

Following publication of a study by Block et al.¹ containing expanded spectroscopic and crystallographic analyses, it has become clear that the data originally reported do not unambiguously support the formation of stable non-cyclic 1,2-disulfoxides. The revised structural assignments undermine the principal conclusions of the 2014 article. The authors apologise to the community for any inconvenience caused.

All co-authors agree to this retraction.
