Application

iPr-NDI is a ligand that when mixed with NiBr2, generates an active dinuclear Ni catalyst. The catalyst has been shown to promote a variety of transformations including the cyclopropanation of alkenes and the [4+1] cycloaddition of vinylidenes and dienes.

Azoarenes are valuable chromophores that have been extensively incorporated as photoswitchable elements in molecular machines and biologically active compounds. Here, we report a catalytic nitrene dimerization reaction that provides access to structurally and electronically diverse azoarenes. The reaction utilizes aryl

Dinuclear Ni complexes supported by naphthyridine-diimine (NDI) ligands catalyze the reductive cyclopropanation of alkenes with CH2 Cl2 as the methylene source. The use of mild terminal reductants (Zn or Et2 Zn) confers significant functional-group tolerance, and the catalyst accommodates structurally

Single bonds between carbon atoms are inherently challenging to activate using transition metals; however, ring-strain release can provide the necessary thermodynamic driving force to make such processes favorable. In this report, we describe a strain-induced C-C oxidative addition of norbornadiene.
