my pockets? By employing Suslick's bis‐pocket porphyrin (ttppp), a reactive MCHCO2Etcomplex and a trans‐[M(CHR)(CO)] (M=Ru) complex have been structurally characterized by X‐ray crystal analysis. The sterically encumbered ttppp ligand has a significant impact on both the diastereoselectivity and chemoselectivity in metalloporphyrin‐catalyzed reactions of ethyl diazoacetate with conjugated aryl dienes
