PREPARATION OF PENTAKIS(2,2,2-TRIFLUOROETHOXY) ARSORANE AND LITHIUM HEXAKIS(2,2,2-TRIFLUOROETHOXY) ARSENATE

Abstract

Tris(2,2,2-trifluoroethyl) arsenite, 4, has been synthesized from 2,2,2-trifluoroethanol and arsenic trichloride. When 4 was allowed to react with chlorine, pentakis(2,2,2-trifluoroethoxy)arsorane, 5, resulted. This material reacted with lithium 2,2,2-trifluoroethoxide, 6, to yield lithium hexakis(2,2,2-trifluoroethoxy) arsenate, 7. A ⁷⁵As NMR resonance was observed for this material.
