Reactivity of a Nickelacycle Derived from Aspartic Acid: Alkylations, Insertions, and Oxidations

Nickelacyclic Carboxylates with Pyridine‐Based Ligand Sets – From Mononuclear Complexes to Supramolecular Architectures by Hydrogen Bonding

“…[8,9] Some of those complexes are valuable starting compounds in organic synthesis, for example for the preparation of carboxylic acids or their derivatives. [10][11][12] Furthermore, some nickelacycles can be used as precursors for oligo-nuclear coordination compounds of nickel. [13] We recently reported the preparation of pyridine-stabilized nickelacyclic carboxylates, which proved to be useful starting compounds for ligand-exchange reactions.…”

Dppm stabilized nickelacyclic carboxylates as building blocks of oligonuclear nickel complexes

“…While those complexes are valuable synthons in organic synthesis for the preparation of carboxylic acids or their derivatives [18][19][20], their potential as starting materials in inorganic synthesis has been barely noticed so far.…”

A new set of nickelacyclic carboxylates (“nickelalactones”) containing pyridine as supporting ligand: synthesis, structures and application in C–C– and C–S– linkage reactions

“…Some of these nickelacycles are interesting starting products for the syntheses of saturated or unsaturated carboxylic acids or their derivatives, for example by alkylation with alkyl halides [4,5,[18][19][20][21], insertion of unsaturated compounds (CO [10,14,16,20], CO 2 [16,20,22,23], RNC [24,25], alkenes [12,26], alkynes [18,[27][28][29][30][31][32]) or transmetalation reaction with ZnR 2 [33][34][35]. Furthermore, nickelacyclic carboxylates are also found to be useful reagents for the construction of functionalized steroid side chains [36][37][38].…”
