Abstract The Lewis acids, TiCl 4 , SnCl 4 , TeCl 4 , ZrCl 4 , SiCl 4 , MoCl 5 , SbCl 5 , AlCl 3 and FeCl 3 have been solvolysed in ethylacetate and the corresponding chloroethoxides have been isolated. The reaction type is explained on the basis of the existence of a low concentration of (OC 2 H 5 ) − in pure ethylacetate according to CH 3 COOC 2 H 5 ⇄ CH 3 CO + + OC 2 H − 5 . Conductivities of the solutions of chloroethoxides formed in ethylacetate also indicate that they act as Lewis acids in this solvent. Conductometric titrations of bases with SnCl 2 (OC 2 H 5 ) 2 , SbCl 3 (OC 2 H 5 ) 2 and AlCl 2 (OC 2 H 5 ) are also reported.
