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 Chiral Cobalt(III) Tris(1,2-diamine) Catalysts That Incorporate Nitrogenous Base Containing Anions for the Bifunctional Activation of Nucleophiles and Electrophiles in Enantioselective Addition Reactions, published in 2021-07-02, which mentions a compound: 3222-47-7, mainly applied to chiral diamine cobalt complex preparation; nitroolefin dimethyl malonate cobalt complex catalyst enantioselective Michael addition; ditertiarybutyl azodicarboxylate dicarbonyl compound cobalt catalyst enantioselective Michael addition; bistertiarybutoxycarbonyl hydrazino dicarbonyl compound preparation, Product Details of 3222-47-7.
Here, The lipophilic diastereomeric cobalt complexes Λ or Δ-[Co((S,S)-dpen)3]3+ 2Cl-BArf- (Λ or Δ-(S,S)-23+ 2Cl-BArf-; dpen/BArf- = 1,2-diphenylethylenediamine/B(3,5-C6H3(CF3)2)4-) ,salts of nicotinates, isonicotinates, related sulfonates, and N,N-dimethylaminobenzoate were applied addition reactions. The 6-chloronicotinate salt gaves slower rates and lower ee values, and the 6-aminonicotinate salt gave faster rates and higher ee values. The 6-Me, 2-methoxy, and unsubstituted analogs afforded intermediate results. The 6-aminonicotinate catalyst was applied to additions of di-Me malonate to aryl-substituted nitroolefins and additions of 1,3-dicarbonyl compounds to di-t-Bu azodicarboxylate, with average yields/ee values of 90%/85% and 94%/77%, resp. The authors were unaware of other ionic catalysts for which Bronsted bases was productively incorporated into the anions, which were seldom if ever purposefully functionalized in any manner.
