Selective binding of substrates using sodium salts of linked C3 symmetric aryl oxides
Abstract
Tris(3,5-dialkyl-2-hydroxyphenyl)methanes (tert-butyl, tert-pentyl) react with three equivalents of sodium hydride to give hexanuclear dimers; these bulky aggregates have six well-defined coordination ‘pockets’ which demonstrate selectivity toward a variety of ketones.
