Abstract: Discovered in 2005, cyclic (alkyl)(amino)carbenes (CAACs) are among the most nucleophilic (σ donating) and also electrophilic (π-accepting) stable carbenes known to date. These properties allow them to activate a variety of small molecules and enthalpically strong bonds, to stabilize highly reactive main-group and transition-metal diamagnetic and paramagnetic species, and to bind strongly to metal centers, which gives rise to very robust catalysts. The most important results published up to the end of 2013 are briefly summarized, while the majority of this Review focuses on findings reported within the last three years.

TL;DR: Two-coordinate Cu(I) complexes with redox active ligands in coplanar conformation manifest suppressed nonradiative decay, reduced structural reorganization, and sufficient orbital overlap for efficient charge transfer, which lead to an efficient blue-emitting OLED.

Allene formation by gold catalyzed cross-coupling of masked carbenes and vinylidenes.
TL;DR: This general catalytic protocol directly couples two unsaturated carbon centers to form the three-carbon allenic core and most probably proceeds through an unprecedented “carbene/vinylidene cross-coupling.”

TL;DR: The bisadduct (cAAC)2NiIICl2 [1] was directly synthesized by treating cAAC with NiCl2 as mentioned in this paper, and it was shown that an intermediate containing NiIII was more favored than one with NiIV.
