Abstract
The reaction of cryptophane-O (1) with lithium diphenylphosphide affor ds the hexaphenol (2), which on alkylation with methyl bromoacetate fo llowed by hydrolysis of the intermediate hexaester (3) provides the he xa-acidic cryptophane (4). The latter is soluble in D2O-NaOD at pD app roximate to 7, where it strongly binds the tetramethyl derivatives of silicium, germanium, tin and lead, and the tetraethyl derivatives of s ilicium, germanium and tin.
