A Ni-catalyzed regiodivergent reductive carboxylation of allyl esters with CO2 is mild, user-friendly, and operationally simple.
The reaction is characterized by an exquisite selectivity profile that is dictated by the ligand backbone. Moragas, J. Wu, J. Peng, L. Fu, X. Qi, X. Wu, Org. In an enantioselective iridium-catalyzed allylic alkylation reaction of a masked acyl cyanide MAC reagent, the umpoled MAC synthon serves as a carbon monoxide equivalent. Hethcox, S. Shockley, B. Stoltz, Org. PSiP-pincer type palladium-catalyzed hydrocarboxylation enables an efficient one-to-one coupling reaction of atmospheric pressure carbon dioxide with 1,3-dienes.
Takaya, K. Sasano, N. Iwasawa, Org. This novel CO2-fixation proceeds via hydropalladation of allenes, followed by regioselective nucleophilic addition to CO2 in the presence of an appropriate reducing agent. Esters, carbamates, ketones, and alkenes are tolerated. Takaya, N. Iwasawa, J. Formate salts can serve as hydride as well as a CO2 source in a mild PGeP-palladium complex-catalyzed hydrocarboxylation of allenes through a highly efficient decarboxylation-carboxylation process.
Zhu, J. The palladium-catalyzed cross-coupling of allylic and benzylic halides with N,N-dimethylcarbamoyl trimethyl silane affords tertiary amides in good to excellent yields. Cunico, R. Pandey, J. While monohalolithium carbenoids can be prepared by a smooth lithium-halogen exchange, the preparation of the corresponding dihalo compounds proved to be highly dependent on the base used to realize the deprotonation, with lithium 2,2,6,6-tetramethylpiperidine emerging as optimal.
Pace, L. Castoldi, A. Mamuye, W. Holzer, Synthesis, , 46, Thiourea-based ligands were evaluated for the palladium-catalyzed bis methoxycarbonylation of terminal olefins. The usefulness of these ligands for this reaction is demonstrated by their stability to oxidizing agents, and their superiority in preventing palladium precipitation and double-bond isomerization. Dai, C. Wang, G. Dong, J. Xiang, T. Luo, B. Liang, J. Chen, Z. Yang, Eur. Slutskyy, L. Overman, Org. This transformation tolerates various functional groups.
Denmark, M. Ahmad, J. In a palladium-catalyzed intermolecular aminocarbonylation of alkenes, the use of hypervalent iodine reagent can accelerate the reaction. Cheng, X. Qi, M. Li, P. Chen, G. The reaction of chiral 1-aminoalkylepoxides with CO2, generated from acidic treatment of an aqueous solution of NaHCO3 at room temperature, efficiently afforded enantiopure cyclic carbonates with total selectivity.
Carbonates were readily transformed into the corresponding diols by reaction with LiAlH4 or by basic hydrolysis. The rapid halogen-metal exchange with alkyllithium and Grignard reagents allows Barbier-type reactions with various electrophiles. Fleming, Z. Zhang, W. Liu, P. Knochel, J. Functional groups, such as nitro, cyano, halogen, ester, and alkoxy groups, are tolerant to the reaction conditions employed. The course of the reaction is highly dependent on the structure of the isocyanide.
