An electron rich, new co-operative iridium(III) complex catalysed tandem conversion of α,β-unsaturated ketones to the α-methylated ketones is described using methanol. Employing this chemoselective protocol, reductive methylation of a wide range of chalcone derivatives, variety of aryl and aliphatic fragment containing α,β-unsaturated ketones along with few biologically important molecules were effectively
使用甲醇描述了一种富电子的新型合作铱 (III) 配合物催化 α,β-不饱和酮到 α-甲基化酮的串联转化。采用这种化学选择性方案,有效地进行了广泛的查耳酮衍生物、各种芳基和脂肪族片段的还原甲基化,这些片段包含 α,β-不饱和酮以及一些生物学上重要的分子。完成了几个对照实验、动力学研究、Hammett 研究和 DFT 计算,以理解这种合作的铱 (III) 催化的 α,β-不饱和酮的串联还原甲基化。
