Lu, Zhenpin Wang, Yuwen Liu, Jia Lin, Yue-jian Li, Zhen Hua Wang, Huadong Synthesis and Reactivity of the CO<sub>2</sub> Adducts of Amine/Bis(2,4,6-tris(trifluoromethyl)phenyl)borane Pairs Frustrated Lewis pairs (FLPs) comprised of bis­(2,4,6-tris­(trifluoromethyl)­phenyl)­borane (<b>1</b>) and a secondary amine (such as HN<i>i</i>Pr<sub>2</sub> or HNEt<sub>2</sub>) readily react with CO<sub>2</sub> at room temperature to afford ammonium carbamatoborate salts <b>2</b>. When the reaction was carried out at 80 °C, carbamate boryl esters <b>3</b> were obtained with release of 1 equiv of H<sub>2</sub>. The <i>i</i>Pr-substituted carbamate boryl ester <b>3a</b> can function as an intramolecular FLP to activate H<sub>2</sub>, affording ammonium borylformate salt <b>4a</b> and formamide adduct <b>5a</b>. Two reaction pathways leading to the formation of <b>4a</b> and <b>5a</b> are proposed. ammonium carbamatoborate salts 2.;Reactivity;carbamate boryl esters 3;amine;H 2.;HNEt;formamide adduct 5;Synthesi;CO 2 Adducts;bi;formation;HNiPr 2;intramolecular FLP;CO 2;reaction pathways;1 equiv;ammonium borylformate salt 4;Lewis;room temperature;Amine;release;PairsFrustrated 2013-11-25
