Presented in this paper is photoinduced hydroxylation of organic halides, providing a mild access to a range of functionalized phenols and aliphatic alcohols. These reactions generally proceed under mild reaction conditions with no need for a photocatalyst or a strong base and show a wide substrate scope as well as excellent functional group tolerance. This work highlights the unique role of NaI that allows a challenging transformation to proceed under mild reaction conditions.

A highly effective hydroxylation reaction of aryl halides with water under synergistic organophotoredox and nickel catalysis is reported. The OH group of the resulting phenols originates from water, following deprotonation facilitated by an intramolecular base group on the ligand. Significantly, aryl bromides as well as less reactive aryl chlorides served as effective substrates to afford phenols with a wide range of functional groups. Without the need for a strong inorganic base or an expensive noble-metal catalyst, this process can be applied to the efficient preparation of diverse phenols and enables the hydroxylation of multifunctional pharmaceutically relevant aryl halides.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 19301-35-0 is helpful to your research. Reference of 19301-35-0

This work focuses on the development of specific substrates for estrogen sulfotransferase (SULT1E1) to produce molecular imaging probes for this enzyme. SULT1E1 is a key enzyme in estrogen homeostasis, playing a central role in the prevention and development of human disease. In vitro sulfation assays showed alkyl and aryl substitutions to a fused heterocyclic system modeled after beta-naphthol (betaN), based on compounds that interact with the estrogen receptor, rendered several molecules with enhanced specificity for SULT1E1 over SULT1A1*1, SULT1A1*2, SULT1A3, and SULT2A1. Several 6-hydroxy-2-arylbenzothiazoles tested demonstrated excellent affinity – V max/Km ratios – and specificity for SULT1E1. Km values ranged from 0.12-2.36 muM. A strong correlation was observed between polarity of the 4?-sustituent on the 2-aryl moiety (Hammett sigmap) and the log(Vmax/Km) (r = 0.964). Substrate sensitivity is influenced by the acidity of the 6-phenolic group demonstrated by correlating its 1H NMR chemical shift (deltaOH) with the log(V max/Km) (r = 0.963). Acidity is mediated by the electron withdrawing capacity of the 4?-substituent outlined by the correlation of the C-2 13C NMR chemical shift (deltaC2) with the log(Vmax/Km) (r = 0.987). 2-[4-(Methylamino)phenyl]-6- hydroxybenzothiazole (2b) was radiolabeled with carbon-11 (11C-(2b)) and used in vivo for microPET scanning and tissue metabolite identification. High PET signal was paralleled with the presence of radiolabeled 11C-(2b)-6-O-sulfate and the SULT1E1 protein detected by western blot. Because this and other members of this family presenting specificity for SULT1E1 can be labeled with carbon-11 or fluorine-18, in vivo assays of SULT1E1 functional activity are now feasible in humans.

Heating acetoxybenzothiophens with AlCl3-benzene can give the normal Fries-rearranged products (for the 4-OAc and 7-OAc isomers); these sometimes react further to give their 2,3-dihydro- (for 4-OAc and 7-OAc) or 2-phenyl derivatives (for 6-OAc).Alternatively, benzene can add across the 2,3-double bond of the acetoxy-compound, to give the 2- (for 6-OAc) or 3-phenyl-2,3-dihydrobenzothiophens (for 7-Oac).With AlCl3 in dichloromethane, 6-acetoxybenzothiophen undergoes intermolecular transfer of an acetyl group to give a mixture of 6-acetoxy-2- and 3-acetylbenzothiophens and 6-hydroxybenzothiophen.With AlCl3 in benzene at room temperature, 4-acetoxybenzothiophen gives a rearranged product, 4,5-dihydro-2,4-diphenylbenzothiophen-7(6H)-one (3a) (17percent).In the presence of AlCl3 for 0.5 h, 4-, 5-, 6-, and 7-hydroxybenzothiophens undergo addition of benzene or toluene, to give the appropriate 2-aryl-2,3-dihydrohydroxybenzothiophens (1).Yields are high for the 4- and 6-hydroxy-isomers (80-85percent), but lower for the 5- (55percent) and 7-isomers (10percent).In each of these reactions the starting hydroxybenzothiophen is partly converted into its 2,3-dihydro-derivative. 5- and 7-Hydroxybenzothiophen also each give the same 4,5-dihydro-2,4-diarylbenzothiophen-7(6H)-one (3) (25percent) in this reaction.When the reaction period with benzene or toluene is extended to 5 days, the amount of solvent addition product (1) decreases, but all four hydroxy-isomers now give the same rearranged product (3).The mechanism of this unusual rearrangement is discussed in terms of a spiro-intermediate.
