Intramolecular Coordination in Organotin Chemistry

摘要: Publisher Summary This chapter overviews organotin compounds containing C,Y-chelating ligands particularly, (1) structures in the solid state, (2) fluxional behavior solution, and (3) stereochemical aspects. Attention is also given to enhanced reactivity of tin–carbon bonds tetraorganotin as a result intramolecular coordination. The first example an compound having ligands, i.e., bis [1, 2-bis(ethoxycarbonyl)ethyl]tin dibromide, for which structure state was unambiguously established by X-ray crystal determination. By using steric electronic properties organometallic that have interesting special reactivities can be isolated. Special features some these are stabilization metal has unusual oxidation number, e.g., Fe(II1) , Co(I1) Ni(II1); trapping species supposed intermediates reactions, organoplatinum di-iodine molecule coordinated end-on platinum step oxidative-addition reactions; use novel organonickel catalyst selective Karasch addition polyhaloalkanes olefines ; (4) unexpected organocopper toward acetylenes.
