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 How Cationic Metalloligands Affect the Coordination of Lewis Basic Ligands in RhI Complexes, published in 2021-12-13, which mentions a compound: 36620-11-8, mainly applied to pyridylphosphine rhodium cationic metalloligand Lewis basic preparation crystal structure; hydroformylation catalyst phosphinopyridine rhodium cationic complex preparation; crystal mol structure phosphinopyridine rhodium metalloligand zinc magnesium complex, Category: quinuclidine.

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.

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

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

C.; Willis, Michael C., which mentions a compound: 36620-11-8, SMILESS is [F-][B+3]([F-])([F-])[F-].C12=C3[Rh+]14567(C8=C5C9C6=C7C8C9)C%10=C4C2CC3%10, Molecular C14H8BF4Rh, SDS of cas: 36620-11-8.

Rhodium-catalyzed hydroacylation using alkynes substituted with pendant nucleophiles, delivers linear α,β-unsaturated enone intermediates with excellent regioselectivity. These adducts are used to construct a broad range of diversely substituted, saturated O-, N- and S-heterocycles in a one-pot process. Judicious choice of cyclisation conditions enabled isolation of O-heterocycles with high levels of diastereoselectivity. A variety of derivatization reactions are also performed, generating functionalized hydroacylation products. This sequence serves as a general approach for the synthesis of fully saturated heterocycles.

Quality Control of Bis(norbornadiene)rhodium (I) tetrafluoroborate. The fused heterocycle is formed by combining a benzene ring with a single heterocycle, or two or more single heterocycles. 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.
