Catalytic Hydrogenations of Organic and Inorganic C=O Bonds

新的三烷基锡[R3Sn]+三氟酸盐、三氟酸盐和四（氟芳基）硼酸盐将使用成熟的有机锡合成化学方法合成，这种方法可以获得锡氢化物（简单的无机还原）和其他反离子（盐分解）。在催化直接加氢条件下（H2，升高T），与有机羰基，酯和酰胺的反应将主要通过1H和119Sn NMR进行监测。同样的锡催化剂将用于CO还原，也将利用共催化简单过渡金属羰基[例如Fe(CO)5, Co2(CO)8]，并将在4-150 bar的合成气（CO+H2） 100-200℃下进行；这将通过原位气相色谱-质谱/红外分析（合作Christopher Tighe，化学工程）以及产品混合物的1H和13C核磁共振波谱来监测。

New trialkylstannylium [R3Sn]+ triflates, triflimides, and tetra(fluoroaryl)borates will be synthesised using well-established organotin synthetic chemistry, which allows access to tin hydrides (simple inorganic reductions) and other counterions (salt metathesis). Reactions under catalytic direct hydrogenation conditions (H2, elevated T), with organic carbonyls, esters, and amides will be monitored primarily with 1H and 119Sn NMR. The same tin catalysts will be used for CO reduction, which will also utilise co-catalytic simple transition metal carbonyls [e.g. Fe(CO)5, Co2(CO)8] and will be carried out at 4-150 bar of syngas (CO+H2) 100-200 degrees C; this will be monitored by in situ GC-MS/IR analysis of gas aliquots (collaboration Christopher Tighe, Chem Eng) alongside 1H and 13C NMR spectroscopy of products mixtures.
