Cage Alkyl Carbenes Provide Experimental Evidence for Isotope-Controlled Selectivity in Competing Tunneling Reactions Open
We report the synthesis and reactivity of adamantylidene (1) and pentacyclo[5.4.0.02,6.03,10.05,9]undecanylidene (2) under matrix isolation conditions. The latter previously unreported carbene is persistent under cryogenic conditions and h…

Cage Alkyl Carbenes Provide Experimental Evidence for Isotope-Controlled Selectivity Open
We report the gas-phase synthesis and reactivity of adamantylidene and pentacyclo[5.4.0.02.6.03.10.05.9]undecanylidene. The latter, a previously unreported carbene, represents only the second alkyl carbene spectroscopically characterized t…

Competitive Heavy‐Atom Tunneling Reactions Controlled Through Electronic Effects Open
Controlling QMT reactivity remains exceptionally challenging and largely unexplored, as it requires rationales distinctly different from those used for classical chemical reactivity. Herein, we investigated how QMT reactivity can be contro…

Equilibrating parent aminomercaptocarbene and CO<sub>2</sub> with 2-amino-2-thioxoacetic acid <i>via</i> heavy-atom quantum tunneling Open
A novel heterosubstituted carbene spontaneously binds CO 2 in a tunneling reaction under cryogenic conditions.

Octave-spanning emission across the visible spectrum from single crystalline 1,3,5,7-tetrakis-(p-methoxyphenyl)adamantane Open
Sustainable efficient light emitters based solely on elements-of-hope are needed to replace current compounds based on less-abundant materials. Functionalized diamondoids are a potential solution for this challenge, as a prototypical examp…

Regioselective Synthesis of <i>meta</i>‐Tetraaryl‐Substituted Adamantane Derivatives and Evaluation of Their White Light Emission Open
New meta‐ substituted tetraaryl adamantane derivatives were synthesized through one‐step Friedel‐Crafts adamantylation by using AlCl 3 in combination with t‐ butyl bromide. The products exhibit improved (over tetraphenyl adamantane) highly…
