Abstract
Abstract A novel scandium(III) complex with disulfonates as counter anions, [Sc(μ-OH)(H 2 O) 5 ] 2 [O 3 S(CF 2 ) 3 SO 3 ] 2 ( 5 ), was prepared from scandium oxides (Sc 2 O 3 ) and perfluoropropane-1,3-disulfonic acid ( 1 , HO 3 SCF 2 CF 2 CF 2 SO 3 H). By X-ray analysis, 5 was found to be a μ-OH-bridged dimeric structure bearing two perfluoropropane-1,3-disulfonates without bonding to scandium(III) centers. A series of lanthanide(III) complexes were also prepared from 1 and lanthanide oxides (Ln 2 O 3 ; Ln = La, Nd, Sm, and Gd). In sharp contrast to the dimeric scandium(III) complex, the corresponding lanthanide(III) complexes had monomeric structures. Interestingly, the dimeric scandium(III) complex, but not the monomeric lanthanide complexes, with perfluoropropane-1,3-disulfonates served as an efficient Lewis acid catalyst for the hydrolysis of esters.
