Název v původním jazyce

Structural Study of some 2,6-Bis[(dimethylaminomethyl)phenyl]butyl Stannanes. Nonconventional Behaviour of Triorganotin (IV) Halides

Popis výsledku v původním jazyce

The four organotin (IV) compounds ([2,6-bis(dimethylaminomethyl)phenyl](n-butyl)R1R2stannane, where R1 = R2 = nBu (1), R1 = nBu, R2 = Cl (2), R1 = nBu, R2 = Br (3) and R1 = R2 = Br (4)), have been prepared and their structures have been investigated in various solvents and at various temperatures (NMR). The structures of these compounds in solution are solvent- and temperature-dependent. The solid state structures of 2 and 3 were studied using CP/MAS NMR spectroscopy and X-ray diffraction techniques. The tetraorganotin compound 1 exhibits tetrahedral geometry with very weak Sn-N coordination. The dynamic process of Sn-N bond(s) association/dissociation was observed using low-temperature NMR measurements. The tin central atom in 2 and 3 is [4+2]-coordinated in toluene solutions and the NMR low-temperature measurements reveal the same dynamic behavior as for 1 in this solution, with retention of the covalent halogen-tin bond. However, this bond is dissociated in methanol solutions, yield
