Lewis-base stabilized diiodine adducts with N-heterocyclic chalcogenamides

Oxidation reactions of stable chalcogenamides with iodine are intriguing due to their broad application in various organic syntheses. In the present study we report on the utilization of N-heterocyclic carbene and cyclic-alkyl-amino carbenes L1-3/su

Photochemical activation of SF6 by N-heterocyclic carbenes to provide a deoxyfluorinating reagent

The activation of the greenhouse gas SF6 using electron-rich N-heterocyclic carbenes gave 2,2-difluoroimidazolines or 2,2-difluoroimidazolidines as well as 2-thio derivatives of the carbene precursors. The N-heterocyclic carbenes can also convert SF4 to give similar products. The difluoroimidazolidine derivatives were applied in deoxyfluorination reactions. Furthermore, the activation of SF6 and the fluorination can be coupled in a one-pot process to convert 1-octanol into 1-fluorooctane.

Saturated NHC Derived Dichalcogen Dications

Herein, the synthesis and characterization of dicationic dichalcogenide compounds [(SIPr)E]2(OTf)2 (3a-E) (E = S, Se, Te) based on a saturated N-heterocyclic carbene (NHC), SIPr [SIPr = C{N(Dipp)CH2}2, Dipp = 2,

Continuous Flow Synthesis of Sulfur- and Selenium?NHC Compounds (NHC=N-Heterocyclic Carbene)

The first continuous flow syntheses of sulfur- and selenium?NHC (NHC=N-heterocyclic carbene) adducts in unprecedented short reaction times and high yields are reported. The importance of these species in coordination chemistry or as efficient tools for determining the π-acceptor character of NHC ligands make any improvement in their synthesis a worthy goal. Thiourea derivatives bearing both saturated and unsaturated NHCs were obtained using NEt3 as a weak base (homogeneous setup) in conjunction with a bed of elemental sulfur (S8). The synthetic route proving optimal for selenoureas involves the use of a simple Se/K2CO3 heterogeneous microreactor design.

A Mechanistically and Operationally Simple Route to Metal–N-Heterocyclic Carbene (NHC) Complexes

We have been puzzled by the involvement of weak organic and inorganic bases in the synthesis of metal–N-heterocyclic carbene (NHC) complexes. Such bases are insufficiently strong to permit the presumed required deprotonation of the azolium salt (the carbe

Straightforward access to chalcogenoureas derived from N-heterocyclic carbenes and their coordination chemistry

Chalcogen-based urea compounds supported by a wide range of N-heterocyclic carbenes are synthesised and fully characterised. Coordination of selenoureas is further explored with Group 11 transition metals to form new copper, gold and silver complexes. Sin

Facile Construction of Yttrium Pentasulfides from Yttrium Alkyl Precursors: Synthesis, Mechanism, and Reactivity

Treatment of the yttrium dialkyl complex TpMe2Y(CH2Ph)2(THF) (TpMe2 = tri(3,5 dimethylpyrazolyl)borate, THF = tetrahydrofuran) with S8 in a 1:1 molar ratio in THF at room temperature afforded a yttrium pentasulfide TpMe2Y(κ4-S5) (THF) (1) in 93% yield. The yttrium monoalkyl complex TpMe2CpYCH2Ph(THF) reacted with S8 in a 1:0.5 molar ratio under the same conditions to give another yttrium pentasulfide [(TpMe2)2Y]+[Cp2Y(κ4-S5)]? (10) in low yield. Further investigations indicated that the S52- anion facilely turned into the corresponding thioethers or organic disulfides, and released the redundant S8, when it reacted with some electrophilic reagents. The mechanism for the formation of the S52- ligand has been investigated by the controlling of the reaction stoichiometric ratios and the stepwise reactions.

Oxygen-atom insertion of NHCecopper complex: The source of oxygen from N, N-dimethylformamide

An unprecedented protocol for oxygen-atom insertion reaction of NHCecopper complexes has been developed by employing N,N-dimethylformamide as the oxygen source, which allows the preparation of imidazolinones from carbene complexes and decodes one of the m

Insight into the role of the counteranion of an imidazolium salt in organocatalysis: A combined experimental and computational study

N-Heterocyclic carbenes (NHCs) can serve as very reactive nucleophilic catalysts and exhibit strong basicity. Herein, we initiate a combined experimental and computational investigation of the NHC-catalyzed ring-closing reactions of 4-(2-formylphenoxy)but
