REDUCTIVE ELIMINATION WITHIN THE CHEMISTRY OF DOUBLY C,N-CHELATED TIN(II/IV) SPECIES	Success in the activation of various small molecules, such as dihydrogen or ammonia1 and tin–halide-promoted C–H bond activation as well as the addition of tin compounds to unsaturated systems has led to renewed studies of the chemistry of Group-14 metals and/or metalloids. The oxidative-addition reaction of appropriate species to various lowvalent metal centres is well established mainly for noble metals as the key step of many catalytic cycles, but this phenomenon is also vigorously studied for some main-group elements,2 where the oxidation of Sn(II) species (stannylenes) to Sn(IV) products (stannanes) is of a major interest. We have already studied potential catalytic activity of some original organotin(IV) species bearing the 2-(N,N-dimethylaminomethyl)phenyl as a C,Nchelating ligand(s) (LCN) within the direct synthesis of dimethyl carbonate from methanol and carbon dioxide.3 As a continuation of our work within the fundamental research, we now present new examples of both oxidative addition4 and reductive elimination involving the doubly C,N-chelated tin(II/IV) species which may bring new insights to this field of chemistry also from the catalytic point of view.
