Carbene Chemistry: From Fleeting Intermediates to Powerful Reagents
Matrix isolation of highly electrophilic carbenes observing invisible carbenes by trapping them with pyridine carbenic philicty approach to a persistent triplet carbene diaminocarbenes exploringExpand
Facile Splitting of Hydrogen and Ammonia by Nucleophilic Activation at a Single Carbon Center
It is shown that more nucleophilic and electrophilic (alkyl)(amino)carbenes can activate H2 under mild conditions, a reaction that has long been known for transition metals. Expand
Cyclic (alkyl)(amino)carbenes (CAACs): stable carbenes on the rise.
This Account discusses another class of stable cyclic carbenes, namely, cyclic (alkyl)(amino)carbenes (CAACs), and shows that the peculiar electronic and steric properties of CAACs allow for the stabilization of unusual diamagnetic and paramagnetic main group element species. Expand
Synthesis and Characterization of a Neutral Tricoordinate Organoboron Isoelectronic with Amines
The synthesis of a neutral tricoordinate boron derivative is reported, which acts as a Lewis base and undergoes one-electron oxidation into the corresponding radical cation. Expand
Cyclic (Alkyl)(amino)carbenes (CAACs): Recent Developments.
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. Expand
Cyclopropenylidenes: From Interstellar Space to an Isolated Derivative in the Laboratory
By appending π-electron–donating amino groups to the triangular skeleton, a cyclopropenylidene derivative is prepared that is stable at room temperature and does not require a heteroatom adjacent to the electron-deficient carbon to confer stability. Expand
Intramolecular "hydroiminiumation" of alkenes: application to the synthesis of conjugate acids of cyclic alkyl amino carbenes (CAACs).
The preliminary results on the scope of the thermally induced hydroiminiumation reaction and its application to the synthesis of a variety of CAAC precursors are reported, which have shown that CAACs can compete with N-heterocyclic carbenes (NHCs)[13] as ligands for transition-metal-based catalysts and also allow the preparation of very low coordinate transition- metal centers.

Aluminum Chloride-Promoted Transamidation Reactions
Aluminum chloride-amine complexes promote transamidation reactions of primary, secondary, and tertiary amides. Combining this method with the known activating effect of an electron-withdrawing groupExpand
Synthesis of a room-temperature-stable dimeric copper(I) hydride.
The preparation, single-crystal X-ray diffraction study, and surprising reactivity of a room-temperature-stable [(CAAC)CuH]2 complex are reported. Expand
