Pushing back the limits: A novel catalytic transformation has been designed to prepare formamidine derivatives by reduction of substituted ureas with hydrosilanes. Simple iron catalysts based on commercially available iron salts and phosphine ligands prove to be highly active in promoting this new hydrosilylation reaction.
突破极限:已设计出一种新颖的催化转化方法,可通过用氢硅烷还原取代的尿素来制备甲am衍生物。事实证明,基于市售铁盐和膦配体的简单铁催化剂在促进这种新的氢化硅烷化反应中具有很高的活性。
