Reductive coupling of diisopropylcarbodiimide by a dirhenium carbonyl complex

Diverse Reactions of α‐Diimine‐Ligated MgI−MgI‐Bonded Compound with Carbodiimides

“…A number of metal complexes, including those of Ti, U, Re, Sm, Nd, etc., have been obtained with the coupled [C 2 (NR) 4 ] moiety as a bridging ligand in the diamide or diamidinate fashion [3,4] . For the metal−metal‐bonded compounds, insertion of carbodiimides into two metal centers is more common, [9] while coupling reaction is rare [3d] . In the case of the β‐diketiminate Mg−Mg‐bond compound, the CyN=C=NCy molecule inserts into two Mg atoms to form the asymmetric dinuclear species [9b,c] .…”

“…All these activation pathways are of great interest because they can provide versatile structural motifs in coordination and organometallic chemistry. On the other hand, the dinuclear metal−metal‐bonded compounds with low‐valent metal centers have shown good reactivity toward heteroallenes, including insertion, coupling, or cycloaddition of the substrate [3d, 7a,9,10,11d] . Specifically, reactions of Mg−Mg‐bonded compounds with different heteroallenes, such as isocyanates RNCO, [7a,9c,10a,11i] CO 2 , [10b,c] SO 2 , [10b] O=C=CPh 2 and MesN=C=CPh 2 , [10b] have been well studied.…”
