摘要本文研究了Fe-PNP钳形配合物(1)在胺修饰的氧化石墨烯载体上的固定化，为Suzuki联芳基交叉偶联反应提供了一种有用的非均相催化剂。络合物1不是在报道的条件下形成的，而是七水合硫酸铁的起始物质（黑铜矿）经过部分脱水得到四水合硫酸铁（菱铁矿）。辉钼矿和黑钼矿都没有催化能力。图形抽象
AbstractWe examined the synthetic and catalytic claims that immobilization of an Fe-PNP pincer complex (1) on an amine-modified graphene oxide support yields a useful heterogeneous catalyst for the Suzuki biaryl cross-coupling reaction. Complex1is not formed under the reported conditions, rather the iron sulfate heptahydrate starting material (melanterite) undergoes partial dehydration to give iron sulfate tetrahydrate (rozenite). Neither rozenite nor melanterite are catalytically competent.Graphic Abstract
