General Description

(4'-Fluorobiphenyl-4-yl)-methanol is a chemical compound with the molecular formula C13H11FO that consists of a fluorobiphenyl moiety attached to a methanol group. It is commonly used in organic synthesis as a building block for the preparation of pharmaceuticals, agrochemicals, and materials. (4'-FLUOROBIPHENYL-4-YL)-METHANOL has the potential for various applications due to its unique chemical structure and properties. Additionally, it may also serve as a useful intermediate in the synthesis of complex organic molecules. However, it is important to handle this chemical with care and follow proper safety protocols when working with it in the laboratory.

Check Digit Verification of cas no

The CAS Registry Mumber 147497-56-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,7,4,9 and 7 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 147497-56:
(8*1)+(7*4)+(6*7)+(5*4)+(4*9)+(3*7)+(2*5)+(1*6)=171
171 % 10 = 1
So 147497-56-1 is a valid CAS Registry Number.

New Bidentate N-Sulfonyl-Substituted Aromatic Amines as Chelate Ligand Backbones: Pd Catalyst Generation in C-C Coupling via in Situ and Precatalyst Modes

Oloyede, Hammed Olawale,Akong Akong, Raymond,Woods, Joseph Anthony Orighomisan,G?rls, Helmar,Plass, Winfried,Eseola, Abiodun Omokehinde

, p. 101 - 110 (2020/07/28)

A series of six new, bidentate ligands based on N-(2-(R-sulfonamido)benzyl)R-sulfonamide have been isolated as dianionic or monoanionic chelators via condensation of 2-(aminomethyl)aniline with sulfonyl chloride reagents; R = methyl (1 and 1′), tolyl (2 and 2′), 2,4,6-Trimethylphenyl (3), or 2,4,6-Triisopropylphenyl (4). Complexes of ligands 2-4 reacted at room temperature with palladium(ii) acetate in the presence of various monodentate N-donor co-ligands to form complexes Pd2(2dmap), Pd2′(OAc.py), Pd3(2acn), Pd3(2py), Pd4(2acn), and Pd4(2py), which were structurally confirmed by three X-ray crystal analyses. Results of catalysis studies in water showed high turnover frequencies and yields of up to 98 % within 10 min and at 0.2 mol-% palladium catalyst loading. Relative to ligand-free catalysis in the presence of only Pd(OAc)2, the ligand-supported palladium species clearly possess positive catalytic advantage. Furthermore, Suzuki coupling efficiencies by 1: 1 'Pd(OAc)2 + ligand' yielded notably better outcomes than for the 1: 2 'Pd(OAc)2 + ligand' in situ catalyst generation, which reveals that coordinative saturation is undesirable. The size of the complementing monodentate co-ligand was observed to influence the catalytic efficiency such that bulkier co-ligands consistently yielded improved turnover frequency values, which leads to the conclusion that steric repulsion between the synthesised ligands and the bulkier co-ligands aided the generation of vacant coordination sites for the more active complexes. Moderate Heck coupling activity was recorded for the complexes and better activities appear to correlate with moderate bulkiness of ligand 3.

N-donor 2-(Sulfonamido)benzamide ligands, their palladium(II) coordination species and C–C coupling catalysis efficiencies

Oloyede, Hammed Olawale,G?rls, Helmar,Orighomisan Woods, Joseph Anthony,Plass, Winfried,Eseola, Abiodun Omokehinde

, p. 336 - 344 (2019/07/31)

A series of synthetically accessible ligands based on new 2-(R-sulfonamido)benzamide have been prepared (R = methyl for H3M; R = 4-toly for H3T and T2CN; R = 2,4,6-triisopropylphenyl for H3iP and HiPCN). The R-substituents were selected to vary in sizes. Allowing ligand H3iP and palladium acetate to stand in solvent leads to self-assembly of the well-defined solvent- and stoichiometry-controlled tetranuclear or hexanuclear coordination macromolecules Pd4(iP)2 and (PdHiP)6, which were analysed by X-ray crystallography. It was observed that palladium active species for Suzuki coupling catalysis could be stabilized by these simple and synthetically assessable N-donor ligands as revealed by turnover frequencies reaching 5500 h?1. Electronic features of these N-donors appear to be more important than the steric properties.
