Ethylacetate as a polar solvent. V. Solvolytic reactions in ethylacetate and the nature of the solvolysed products

Abstract

The Lewis acids, TiCl4, SnCl4, TeCl4, ZrCl4, SiCl4, MoCl5, SbCl5, AlCl3 and FeCl3 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 (OC2H5)- in pure ethylacetate according to CH3COOC2H5 CH3CO+ + OC2H5-. 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 SnCl2(OC2H5)2, SbCl3(OC2H5)2 and AlCl2(OC2H5) are also reported
