On April 30, 2020, Vol’eva, V. B.; Zhorin, V. A.; Ovsyannikova, M. N.; Kurkovskaya, L. N. published an article.Computed Properties of 96-76-4 The title of the article was Solid-Phase ortho-Hydroxylation of 2,4-Di-tert-butylphenol and Its Derivatives. And the article contained the following:

Direct phenol-catechol conversion was realized as a result of the solid-phase reaction of 2,4-di-tert-butylphenol with cuprous oxide under high pressure and shear deformation on the Bridgman anvils. The yield of 3,5-di-tert-butylcatechol in this reaction was about 85%. When cupric oxide was used in the solid-phase process, oxidative coupling of the starting phenol took place, resulting in quant. formation of tetra-tert-butyl-ortho-bisphenol. The reaction of 6-substituted derivatives of 2,4-di-tert-butylphenol with cuprous oxide was used as an example to demonstrate the possibility of substitutive ortho-hydroxylation yielding 7-20% of pyrocatechols. The experimental process involved the reaction of 2,4-Di-tert-butylphenol(cas: 96-76-4).Computed Properties of 96-76-4

On December 31, 2021, Bhanderi, Khushboo; Ghalsasi, Prasanna S.; Inoue, Katsuya published an article.Computed Properties of 96-76-4 The title of the article was Nonconventional driving force for selective oxidative C-C coupling reaction due to concurrent and curious formation of Ag0. And the article contained the following:

Herein, reduction of [Ag(NH3)2]+ to Ag0 with concurrent oxidation of different phenols/naphthols to biphenyls was undertaken. The work was originated during careful observation of an undergraduate experiment-Tollen’s test-where silver mirror film deposition takes place on the walls of borosilicate glass test tube. When the same reaction was carried out in polypropylene (plastic-Eppendorf) tube, aggregation of Ag0 leading to floating Ag-particles was observed but not silver film deposition. This prompted to carry out challenging cross-coupling reaction by only changing the surface of the reaction flask from glass to plastic to silicones. Surprisingly, good selective oxidative homo-coupling on Teflon surface while cross-coupling in Eppendorf vial was observed Thus, the formation of biphenyl is driven by the macroscopic growth of Ag0 into [Ag-particle] orchestrated by Ag…Ag cohesive interaction was proposed. To validate results, experiments were also performed on gram scale. More importantly, oxidation of β-naphthol carried out in quartz (chiral) tube which yielded slight enantioselective excess of BINOL. The experimental process involved the reaction of 2,4-Di-tert-butylphenol(cas: 96-76-4).Computed Properties of 96-76-4

Terashima, Kyu; Kawasaki-Takasuka, Tomoko; Yamazaki, Takashi published an article in 2021, the title of the article was Construction of fully substituted carbon centers containing a heteroatom and a CF3 group via in situ generated p-quinone methides.Formula: C10H22S And the article contains the following content:

1,6-Conjugate additions of δ-CF3-δ-substituted p-quinone methides, generated in-situ from silyl ethers I (R1 = Me, n-Pr, i-Pr, Ph, PhCC), have been achieved with a variety of heteronucleophiles under mild conditions, which led to facile and practical construction of the compounds II (X = PhCH2NH, PhNHNH, 1-pyrrolidinyl, 1-imidazolyl, F3CCH2O, PhO, i-PrS, PhS, etc.; R2 = H or TBS) with fully substituted carbon centers including a heteroatom and a CF3 group. In particular, it was revealed that some amines themselves worked for efficient cleavage of the TBS protective group, and addition of a catalytic amount of an appropriate Bronsted acid was found to sometimes improve the progress of the desired process. The experimental process involved the reaction of 1-Decanethiol(cas: 143-10-2).Formula: C10H22S
