HPLC of Formula: 1194-02-1In 2021 ,《Sensitization-initiated electron transfer via upconversion: mechanism and photocatalytic applications》 was published in Chemical Science. The article was written by Glaser, Felix; Kerzig, Christoph; Wenger, Oliver S.. The article contains the following contents:

Sensitization-initiated electron transfer (SenI-ET) describes a recently discovered photoredox strategy that relies on two consecutive light absorption events, triggering a sequence of energy and electron transfer steps. The cumulative energy input from two visible photons gives access to thermodynamically demanding reactions, which would be unattainable by single excitation with visible light. For this reason, SenI-ET has become a very useful strategy in synthetic photochem., but the mechanism has been difficult to clarify due to its complexity. We demonstrate that SenI-ET can operate via sensitized triplet-triplet annihilation upconversion, and we provide the first direct spectroscopic evidence for the catalytically active species. In our system comprised of fac-[Ir(ppy)3] as a light absorber, 2,7-di-tert-butylpyrene as an annihilator, and N,N-dimethylaniline as a sacrificial reductant, all photochem. reaction steps proceed with remarkable rates and efficiencies, and this system is furthermore suitable for photocatalytic aryl dehalogenations, pinacol couplings and detosylation reactions. The insights presented here are relevant for the further rational development of photoredox processes based on multi-photon excitation, and they could have important implications in the greater contexts of synthetic photochem. and solar energy conversion.

Kenari, Marziyeh E.; Putman, Joshua I.; Singh, Ravi P.; Fulton, Brandon B.; Phan, Huy; Haimour, Reem K.; Tse, Key; Berthod, Alain; Lovely, Carl J.; Armstrong, Daniel W. published their research in Molecules in 2021. The article was titled 《Enantiomeric separation of new chiral azole compounds》.HPLC of Formula: 1194-02-1 The article contains the following contents:

Twelve new azole compounds (rec/R/S)-I (Ar = Ph, Bn, Bz, allyl, 3,5-bis(trifluoromethyl)phenyl; R = 2,5-dioxo-1-phenylpyrrolidin-3-yl, 2-ethoxy-1-hydroxy-2-oxoethyl), (rec/R/S)-II (R1 = Ph, 4-chlorophenyl, 4-fluorophenyl, 4-methoxyphenyl) and (rec/R/S)-III were synthesized through an ene reaction involving methylidene heterocycles IV and V and N-phenylmaleimide, producing four oxazoles II (R = 2,5-dioxo-1-phenylpyrrolidin-3-yl), five thiazoles I (R = 2,5-dioxo-1-phenylpyrrolidin-3-yl), and one pyridine derivative, III and Et glyoxylate for an oxazole II (R = 2-ethoxy-1-hydroxy-2-oxoethyl) and a thiazole compd I (R = 2-ethoxy-1-hydroxy-2-oxoethyl). The twelve azoles I, II and III have a stereogenic center in their structure. Hence, a method to sep. the enantiomeric pairs, must be provided if any further study of chem. and pharmacol. importance of these compounds is to be accomplished. Six chiral stationary phases were assayed: four were based on macrocyclic glycopeptide selectors and two on linear carbohydrates, i.e., derivatized maltodextrin and amylose. The enantiomers of the entire set of new chiral azole compounds I, II and III were separated using three different mobile phase elution modes: normal phase, polar organic, and reversed phase. The most effective chiral stationary phase was the MaltoShell column, which was able to sep. ten of the twelve compounds I, II and III in one elution mode or another. Structural similarities in the newly synthesized oxazoles II provided some insights into possible chiral recognition mechanisms. The results came from multiple reactions, including the reaction of 4-Fluorobenzonitrile(cas: 1194-02-1HPLC of Formula: 1194-02-1)

Wang, Chang-Sheng; Yu, Yongqi; Sunada, Yusuke; Wang, Chen; Yoshikai, Naohiko published an article in 2022. The article was titled 《Cobalt-Catalyzed Carbo- and Hydrocyanation of Alkynes via C-CN Bond Activation》, and you may find the article in ACS Catalysis.Related Products of 1194-02-1 The information in the text is summarized as follows:

Cobalt-catalyzed carbo- and hydrocyanation reactions of alkynes via C-CN bond cleavage of organic cyanides are reported. A low-valent cobalt-diphosphine catalyst generated by reduction with Zn promotes the arylcyanation of alkynes with trans-selectivity. By contrast, the addition of Zn(OTf)2 to this catalytic system not only accelerates the transformation but also switches the stereoselectivity, affording cis-arylcyanation products. The present catalytic systems prove to be effective for alkenylcyanation using alkenyl cyanides as well as for transfer hydrocyanation using propionitrile as the HCN surrogate. Exptl. and computational studies on arylcyanation have been performed to gain insight into the reaction pathways, including the possible origin of the stereodivergence under cobalt and cobalt/zinc catalysis.

In 2022,Pan, Liuming; Fu, Wenqian; Zhang, Lei; Wang, Siming; Tang, Tiandi published an article in Molecular Catalysis. The title of the article was 《Highly dispersed Co species in N-doped carbon enhanced the aldehydes ammoxidation reaction activity》.Product Details of 1194-02-1 The author mentioned the following in the article:

Natural vitamin B12 was used as a carbon source for the preparation of a cobalt- and nitrogen-doped catalyst precursor, which was pyrolyzed at different temperatures to obtain cobalt- and nitrogen-doped carbon (Co@NC-T) (T denotes pyrolysis temperature) catalysts. The Co@NC-800 exhibited excellent activity and selectivity in the ammoxidation of aromatic aldehydes with ammonium carbonate to aromatic nitriles compared to the Co@NC-700, Co@NC-600 and Co@NC-500 catalysts. The high catalytic performance of Co@NC-800 could be due to the presence of the low-d. electron cloud of the highly dispersed Co species, which could interact with the benzene ring of benzaldehyde bearing p-π conjugate, thereby promoting the adsorption and activation of benzaldehyde. Consequently, the activated benzaldehyde reacted with amino groups that were decomposed from ammonium carbonate and subsequently underwent a dehydration process to form nitriles.4-Fluorobenzonitrile(cas: 1194-02-1Product Details of 1194-02-1) was used in this study.
