Alkynylation of aldehydes with alkynyl(aryl)iodonium salts catalyzed by an N-heterocyclic carbene (NHC) has been developed. The application of the organocatalyst and the hypervalent iodine group transfer reagent allowed for metal-free C-H functionalization and C-C bond formation. The reaction proceeds under mild conditions, at -40 C and in the presence of an amine base, providing access to an array of heteroaryl-propargyl ketones containing various substituents in good to excellent yields. The mechanism of the reaction was investigated by means of both experiments and density functional theory calculations. 13C-labeling and computations determined that the key alkynyl transfer step occurs via an unusual direct substitution at an acetylenic carbon, wherein an iodine-based leaving group is exchanged by a Breslow intermediate nucleophile. Moreover, kinetic studies revealed that the turnover-limiting step of the catalytic cycle is the generation of the Breslow intermediate, whereas the subsequent C-C bond formation is a fast process. These results are fully reproduced and rationalized by the calculated full free energy profile of the reaction, showing that the largest energy span is located between the protonated form of NHC catalyst and the transition state for the carbene attack on the aldehyde substrate.

Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments.Introducing a new discovery about 10200-59-6, Name is 2-Thiazolecarboxaldehyde, Computed Properties of C4H3NOS.

Metallafuran complexes with a fused five-membered phosphonium ring were synthesized from reactions between terminal ynones HC?C(C=O)R and cis-[Ru/Os(dppm)2Cl2] (dppm=1,1-bis(diphenylphosphino)methane). A metal?vinylidene-involving pathway was found to be an energetically feasible formation mechanism for these complexes. These phosphonium-containing metallafurans, like many phosphonium-functionalized drugs, have the ability to induce mitochondrial dysfunction. They also exhibit stronger cytotoxicity against several human cancer cell lines in comparison with their metal precursors and the classic anticancer drug cisplatin. Overall, this work provides structural and mechanistic insights for the rational design of functional metallacycles via activation of alkynes by RuII and OsII centers.

The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.10200-59-6, Name is 2-Thiazolecarboxaldehyde, molecular formula is C4H3NOS. In a Article£¬once mentioned of 10200-59-6, Computed Properties of C4H3NOS

The results of the reaction of aminomethyl heterocycles and 4,6-dimethyl-2-formylpyrimidine and of activated secondary amines with different aryl/heteroaryl or aliphatic aldehydes and N-methylmaleimide or maleimide are described. In the former case the reactions gave single diastereomers via endo-transition states whilst the latter gave a mixture of diastereomers, which are believed to arise from anti-dipoles via endo/exo transition states. The stereochemistry of the cycloadducts was determined by 1H NMR and confirmed by X-ray crystallography.

Cation-pi-controlled preorientation of (E)-styrylthiazoles was performed in both solution and solid phases. Irradiation of (E)-styrylthiazoles in the presence of HCl produced synHT dimers in good selectivities, while little selectivity was observed without HCl. X-ray structures for the HCl salts of (E)-styrylthiazoles showed a head-to-tail arrangement through cation-pi interactions between the two neighboring molecules. Irradiation of these HCl salts produced synHT dimers in excellent yields.
