Let’s take a look at the latest research on this compound (cas:36620-11-8).

The mechanism of the intramol. enantioselective rhodium(I)-catalyzed hydroboration of NHC-boranes is investigated by exptl. reactivity measurements and mol. electronic structure calculations, within the framework of the D. Functional Theory and the RPA methods. The crucial role of alkene coordination and the origin of enantioselectivity are discussed. Two possible mechanisms are considered, via either prior hydride migratory insertion or boron migratory insertion. The min. energy computed pathway leads to the enantiomer exptl. observed, therefore supporting the hydride migratory insertion mechanism. Calculations of the final steps of the catalytic cycle, i.e. regeneration of the catalyst and release of the product, give us further insights into the mechanism and rationalize the exptl. results.

In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called HMF and furfural: Promising platform molecules in rhodium-catalyzed carbonylation reactions for the synthesis of furfuryl esters and tertiary amides, published in 2020-01-31, which mentions a compound: 36620-11-8, mainly applied to alkyl aryl iodide biomass rhodium carbonylation catalyst; furfuryl ester tertiary amide, Quality Control of Bis(norbornadiene)rhodium (I) tetrafluoroborate.

A biomass involved rhodium-catalyzed carbonylative synthesis of furfuryl esters and tertiary amides has been developed. 5-Hydroxymethylfurfural (HMF) was used as both substrate and CO surrogate for the first time in a carbonylation reaction, and both alkyl and aryl iodides were tolerated well to afford the desired furfuryl esters in moderate to good yields. In addition, furfural was also utilized as a CO source for the synthesis of tertiary amides. A variety of tertiary amides were obtained in moderate to excellent yields with good functional groups compatibility. Notably, tertiary amines were used as the amine source through a C-N bond cleavage pathway in the absence of addnl. oxidant.

Formula: 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 (Z)-Selective Hydroboration of Terminal Alkynes Catalyzed by a PSP-Pincer Rhodium Complex. Author is Lyu, Yanzong; Toriumi, Naoyuki; Iwasawa, Nobuharu.

A highly (Z)-selective hydroboration of terminal alkynes was achieved using a thioxanthene-based PSP-pincer Rh catalyst. This hydroboration exhibited good chemoselectivity toward alkynes over carbonyl compounds such as ketones and aldehydes. The mechanistic studies indicated the involvement of Rh-vinylidene intermediates, and the high (Z)-selectivity could be attributed to the rigid and electron-rich nature of the PSP-Rh catalyst.

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.

Author is Lou, Yazhou; Wang, Jun; Gong, Gelin; Guan, Fanfu; Lu, Jiaxiang; Wen, Jialin; Zhang, Xumu.

The direct catalytic asym. hydrogenation of (Z)-α-dehydroamino boronate esters was realized. Using this approach, a class of therapeutically relevant alkyl-substituted α-amidoboronic esters was easily synthesized in high yields with generally excellent enantioselectivities (up to 99% yield and 99% ee). The utility of the products has been demonstrated by transformation to their corresponding boronic acid derivatives by a Pd-catalyzed borylation reaction and an efficient synthesis of a potential intermediate of bortezomib. The clean, atom-economic and environment friendly nature of this catalytic asym. hydrogenation process would make this approach a new alternative for the production of alkyl-substituted α-amidoboronic esters of great potential in the area of organic synthesis and medicinal chem.
