Abstract

Abstract Cesium 3, 5-bis (2, 4, 6-tri-tert-butylphenyl)-1, 2, 4-triphospholide (12) and cesium 5- (2, 4, 6-tri-tert-butylphenyl) tetraphospholide (13) were synthesized and isolated with flat five- membered rings, which are an indication of the aromaticity in these anions. Compound 13 is the first example of a stable tetraphospholide anion, which is structurally characterized. Kinetic stabilization of the 1, 2, 4-triphospholide system by two supermesityl groups ...
