Reaction of Substituted Hydrazones with Thionyl Chloride and Sulfuryl Chloride

Treatment of acetylhydrazones 2, ethoxycarbonylhydrazones 3, p-tolylsulfonylhydrazones 4 or semicarbazones 5 with thionyl chloride leads to the 1,2,3-thiadiazoles 6a-o.Sulfuryl chloride on the other hand accomplishes the transfer of chlorine without incorporating a sulfur atom.The new synthesized 1,2,3-thiadiazoles 6g-o are characterized in detail by spectroscopic methods.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Formula: C8H6OS, you can also check out more blogs about130-03-0

Direct Carboxylation of Electron-Rich Heteroarenes Promoted by LiO-tBu with CsF and [18]Crown-6

We herein demonstrate that the combination of LiO-tBu, CsF, and [18]crown-6 efficiently promotes the direct C?H carboxylation of electron-rich heteroarenes (benzothiophene, thiophene, benzofuran, and furan derivatives). A variety of functional groups, including methyl, methoxy, halo, cyano, amide, and keto moieties, are compatible with this system. The reaction proceeds via the formation of a tert-butyl carbonate species.

Deprotonative Silylation of Aromatic C-H Bonds Mediated by a Combination of Trifluoromethyltrialkylsilane and Fluoride

A method for the deprotonative silylation of aromatic C-H bonds has been developed using trifluoromethyltrimethylsilane (CF3SiMe3, Ruppert-Prakash reagent) and a catalytic amount of fluoride. In this reaction, CF3SiMe3 is considered to act as a base and a silicon electrophile. This process is highly tolerant to various functional groups on heteroarenes and benzenes. Furthermore, this method can be applied to the synthesis of trimethylsilyl group-containing analogs of TAC-101, which is a bioactive synthetic retinoid with selective affinity for retinoic acid receptor alpha (RAR-alpha) binding. We also report further transformations of the silylated products into useful derivatives.

Rhodium-Catalyzed 1,1-Hydroacylation of Thioacyl Carbenes with Alkynyl Aldehydes and Subsequent Cyclization

A rhodium-catalyzed 1,1-hydroacylation of thioacyl carbenes with alkynyl and alkenyl aldehydes and subsequent 6-endo-trig/dig cyclization are realized, giving structurally diverse 4H-thiopyran-4-ones and 2,3-dihydro-4H-thiopyran-4-ones in moderate to good yields. The oxidative addition of Rh(I) to aldehydes is proposed to be the turnover-limiting step. Manipulations of estrones demonstrate the applications of our formal (3 + 3) transannulations in the structural modifications of natural products.

Cu/Pd-catalyzed C-2-H arylation of quinazolin-4(3H)-ones with (hetero)aryl halides

The regiospecific C-2-H arylation of N-3-substituted quinazolin-4(3H)-ones with a wide range of aryl or (hetero)aryl halides under microwave irradiation was studied. A ligand-dependent palladium/copper bicatalytic system was developed and allowed direct cross-coupling with a variety of (hetero)aryl halides. This useful and scalable procedure promotes the construction of C(sp2)-C(sp2) bonds from arenes or (hetero)arenes and aryl or (hetero)aryl bromides and chlorides in a time-efficient strategy. The extension of the reaction to various N-3-substituted quinazolin-4(3H)-ones with iodobenzene as well as the scope and limitations of the method were also investigated.
