资源简介：
The synthesis, structural
characterization, and acid–base
chemistry of [C(SiMe2OCH2CH2OMe)3]Na (2), a sterically encumbered zwitterionic
organosodium compound, is reported. 2 is a strong Brønsted
base that forms frustrated Lewis pairs (FLPs) with a number of boron-containing
Lewis acids ranging from weakly Lewis acidic aryl and alkyl boranes
to various alkyl borates. These intermolecular FLPs readily cleave
H2, which confirms that even poor Lewis acids can engage
in FLP-mediated H2 cleavage provided that the present bulky
base is of sufficiently high Brønsted basicity.
