Hexanuclear copper hydride complexes, Cu(μ-H)( meso-L)(RNC) (R = Bu (6a), Cy (6b)), were prepared by using a new linear tetraphosphine, meso-PhPCHP(Ph)(CH)P(Ph)CHPPh ( meso-L), and were converted into active catalysts of [Cu(μ-OCH)( meso-L)(RNC)] under the reaction conditions of formic acid dehydrogenation, where unsymmetric dinuclear copper sites supported by the tetradentate phosphine and isocyanide ligands were essential to demonstrate effective catalytic activity.
通过使用一种新型线性四膦配体meso-PhPCHP(Ph)(CH)P(Ph)CHPPh（meso-L）制备了六核氢化铜配合物Cu(μ-H)(meso-L)(RNC)（R = Bu（6a），Cy（6b）），并在甲酸脱氢反应条件下将其转化为[Cu(μ-OCH)(meso-L)(RNC)]活性催化剂，其中由四齿膦配体和异腈配体支撑的不对称双核铜位点对于展现有效的催化活性至关重要。
