    芳烃三氟甲磺酸酯与合并钯和可见光-光氧化还原催化剂的CO 2的羧基化
    摘要:
    我们在此报告了在环境温度和CO 2的球囊压力下,易于获得的芳基三氟甲磺酸酯在可见光促进下的高度实用的羧化反应钯和光氧化还原Ir(III)催化剂的组合使用。令人惊讶的是,化学计量的金属还原剂被非金属的胺还原剂所替代,从而提供了对环境无害的羧化过程。另外,通过后期羧化反应已经完成了直接从苯酚的一锅法合成羧酸和雌酮的修饰以及药用药物阿达帕林和贝沙罗汀的简明合成。此外,已经在H型密闭容器中证明了平行的脱羧-羧化反应,这对战略领域是一个有趣的概念。光谱和光谱电化学研究表明,电子从Ir(III)/ DIPEA组合中转移,生成了芳基羧酸盐和Pd(0)用于催化转换。

    The 14 A octamethyloctahydrodibenzofluorene moiety has been incorporated into a sterically expanded constrained geometry catalyst, Me2Si(eta1-C29H36)(eta1-N-tBu)ZrCl2.OEt2 (1). The solid-state structure suggests that the activated olefin polymerization catalyst is quite spatially accessible, rationalizing its extraordinary reactivity toward alpha-olefins. 1/MAO (MAO = methylaluminoxane) can be more
