The cover picture shows the insertion of a Pt 0 complex fragment into the S–S bond of a 1,2,4‐trithiolane 1‐ S ‐oxide. Reactions of Pt 0 complexes with small sulfur‐containing heterocycles have become more and more popular in order to generate and stabilize reactive sulfur‐containing species. The reaction presented leads to three‐ and four‐membered platinacycles by ring contraction with expulsion of the reactive thiocarbonyl derivatives. The postulated mechanism for the fragmentation of 1,2,4‐trithiolane 1‐ S ‐oxide, as well as the molecular structures, give a reasonable explanation for the observed selectivity. Details are discussed in the article by W. Weigand, G. Mloston et al. on p. 5627 ff. We thank Dr. Jaroslaw Romanski for decorating our Christmas tree (background) for this year and designing the cover picture.
