Since the discovery of the first stable N-heterocyclic carbene (NHC) in the beginning of the
1990s, these divalent carbon species have become a common and available class of …

Isolation and characterization of stable radicals has been a long-pursued quest. While there
has been some progress in this field particularly with respect to carbon, radicals involving …

Carbenes, including N‐heterocyclic carbene (NHC) ligands, are used extensively to
stabilize open‐shell transition metal complexes and organic radicals. Yet, it remains …

Neutral organic super electron donors (SEDs) display impressive reducing power but, until
now, it has not been possible to use them catalytically in radical chain reactions. This is …

The isolation of carbon-centered diradicals is always challenging due to synthetic difficulties
and their limited stability. Herein we report the synthesis of a trans-1, 4-cyclohexylene …

Despite recent advances in the field of cyclic alkyl amino carbenes (CAACs) including a few
complementary synthetic strategies affording CAACs with various substitution patterns, the …

Isomerization Metathesis (ISOMET) reaction is an emerging tool for “open loop” chemical
recycling of polyethylene to propylene. Novel, latent N‐Alkyl substituted Cyclic …

Diradicals have been of tremendous interest for over a century ever since the first reports of
p‐and m‐phenylene‐bridged diphenylmethylradicals in 1904 by Thiele and 1915 by …

We elucidate why some electron rich-olefins such as tetrathiafulvalene (TTF) or paraquat (1,
1′-dimethyl-4, 4′-bipyridinylidene) form persistent radical cations, whereas others such as …

Herein, we report tethered cyclic (alkyl)(amino) carbene (CAAC) dimers in which two CAAC-
motifs are connected by an ethylene-, trans-1, 2-cyclohexylene-and propylene-spacer …
