Aromatic heterocycles are more basic than benzene due to the participation of heteroatoms. Compound: Bis(norbornadiene)rhodium (I) tetrafluoroborate, is researched, Molecular C14H8BF4Rh, CAS is 36620-11-8, about Sequential Catalytic Functionalization of Aryltriazenyl Aldehydes for the Synthesis of Complex Benzenes. Author is Seo, Sangwon; Gao, Ming; Paffenholz, Eva; Willis, Michael C..

We demonstrate that aryltriazenes can promote three distinctive types of C-H functionalization reactions, allowing the preparation of complex benzene mols. with diverse substitution patterns. 2-Triazenylbenzaldehydes are shown to be efficient substrates for Rh(I)-catalyzed intermol. alkyne hydroacylation reactions. The resulting triazene-substituted ketone products can then undergo either a Rh(III)-catalyzed C-H activation, or an electrophilic aromatic substitution reaction, achieving multifunctionalization of the benzene core. Subsequent triazene derivatization provides traceless products.

An asym. intermol. [4 + 2] cycloaddition of 1,3-dienes with dialkyl acetylenedicarboxylates, which was catalyzed by a rhodium(I)-chiral phosphoramidite complex, was developed. This protocol provided a highly enantioselective access to prepare carbonyl substituted cyclohexa-1,4-dienes with up to 96% yield and >99% ee [e.g., di-Me acetylenedicarboxylate + (E)-1,3-nonadiene → I (96%, 99% ee)]. Notably, a cycloaddition on the 10 g scale gave the product in 92% yield and with 99% ee, which showed great potential for the scale-up synthesis of carbonyl substituted cyclohexa-1,4-dienes.

Highly regio- and enantioselective hydrogenation of conjugated α-substituted dienoic acids was realized for the first time using Trifer-Rh complex, providing a straightforward method for the synthesis of chiral α-substituted γ,δ-unsaturated acids. DFT calculations revealed N+H-O hydrogen bonding interaction is formed to stabilize the transition state and the coordination of 4,5-double bond to Rh(III) center would facilitate the reductive elimination process. This hydrogenation provided a gram-scale synthesis of the precursor of sacubitril.

Synthetic Route of C14H8BF4Rh. The mechanism of aromatic electrophilic substitution of aromatic heterocycles is consistent with that of benzene. Compound: Bis(norbornadiene)rhodium (I) tetrafluoroborate, is researched, Molecular C14H8BF4Rh, CAS is 36620-11-8, about Rhodium-catalyzed intramolecular hydroacylation of 1,2-disubstituted alkenes for the synthesis of 2-substituted indanones. Author is Yuan, Jing; Liu, Chong; Chen, Yan; Zhang, Zhenfeng; Yan, Deyue; Zhang, Wanbin.

The intramol. hydroacylation of 1,2-disubstituted alkenes was considered to be a challenging task due to the side reactions resulted from the lack of addnl. substituent at 1-position and the low activity caused by the steric hindrance of substituent at 2-position, and an asym. version was not considered possible due to problems associated with the racemization of the products. The authors have partially solved these problems. Catalyzed by an activated diphosphine-Rh complex and reacted in a selected dihalogenated solvent, the intramol. hydroacylation of o-(2-arylvinyl)benzaldehydes provided the corresponding 2-aryl-1-indanones in high yields, and its asym. variant using o-(2-alkylvinyl)benzaldehydes afforded chiral 2-alkyl-1-indanones in high yields and with moderate enantioselectivities.

The natural nucleoside (+)-sinefungin, structurally similar to cofactor S-adenosyl-L-methionine (SAM), inhibits various SAM-dependent methyltransferases (MTs). Access to sinefungin analogs could serve as the basis for the rational design of small-mol. methyltransferase inhibitors. We developed a route to the unnatural C9′ epimer of sinefungin that employed a diastereoselective Overman rearrangement to install the key C6′ amino stereo-center. The ability for late stage modification is highlighted, opening an avenue for the discovery of new MTs inhibitors.

Author is Gilbert, Sophie H.; Fuentes, Jose A.; Cordes, David B.; Slawin, Alexandra M. Z.; Clarke, Matthew L..

The use of Rh catalysts derived from a phospholane-phosphite ligand were found to be more productive than the classic rhodium/BINAP system in enantioselective conjugate additions These catalysts enable the use of lower amounts of aryl boronic acid in an asym. arylation reaction that required an impractical excess of nucleophile. This catalyst was also found to enable the coupling of a poorly reactive Michael acceptor, N-CBz-2-3-dehydro-4-piperidone, or the coupling of poorly reactive 2-furyl boronic acids at ambient or near temperatures

Epoxy compounds usually have stronger nucleophilic ability, because the alkyl group on the oxygen atom makes the bond angle smaller, which makes the lone pair of electrons react more dissimilarly with the electron-deficient system.

Author is Jiang, Ya-Nan; Li, Ding-Chang; Yang, Ying; Zhan, Zhuang-Ping.

A porous organic polymer (POL-dppe) was synthesized and employed as a heterogeneous ligand for selective hydroacylation of alkynes. The polymer shows high linear selectivity and catalytic efficiency toward a broad range of alkynes and β-S substituted aldehydes. Owing to the confinement effect of the microporous structure, POL-dppe was far superior to the monomeric dppe ligand in controlling the selectivity of electron-deficient alkynes. The use of a porous organic polymer as a regioselective and efficient ligand in hydroacylation is reported for the first time.

A series of RhI complexes featuring cationic diphosphinometal ligands (PMPn+) has been synthesized, and the effect of the dative RhI → Mn+ interactions on other ligands coordinated to the RhI center were studied. The Rh-CO bond strength in square pyramidal [(PMP)Rh(CO)X]n+-type complexes (X = Cl, H) is dominated by the charge of the metalloligand. Complex [(PZnP)Rh(CO)H](NTf2)2 (7) was evaluated for its competence in hydroformylation catalysis. Computational anal. of octahedral [(PMP)Rh(CO)2H]n+ model complexes revealed a strengthening of the Rh-CO bond trans to the metalloligand with increasing at. number of the metalloligand.
