Straightforward synthesis of rubidium bis(trimethylsilyl)amide and complexes of the alkali metal bis(trimethylsilyl)amides with weakly coordinating 2,2,5,5-tetramethyltetrahydrofuran

Abstract

2,2,5,5-Tetramethyl-THF (thf*) is a very bulky ether with a rather poor binding tendency due to weak basicity and steric hindrance. In the solid state, thf* complexes are observed whereas in solution these complexes dissociate.
