4-tert-butylaniline

The feasibility of this approach was demonstrated with a model library of 36 compounds prepared from a combination of three Boc protected L-amino acids (valine 23, phenylalanine 24, and proline 25) and 12 aromatic amines (3,4,5-trimethoxyaniline (26), 3,5-dimethylaniline (27), 3-benyloxyaniline (28), 5-aminoindane (29), 4-tert-butylamline (30), 4-biphenylamine (31), 1-3-benyloxyani-line (28), 5-aminoindane (29), 4-tert-butylaniline (30), 4-biphenylamine (31), 1-aminonaphthalene (32), 4-tritylaniline (33), 2-aminoanthracene (34),... 

The hydrogenation of toluene, aniline, /r-toluidine, and 4-tert-butylaniline was examined over catalyst M1273. The reaction profile for the reactions is shown in Figure 2. From this it can be seen that the order of reactivity is aniline > toluene > /Moluidinc > 4-fer f-butylaniline. The hydrogenation products were methylcyclohexane from toluene, cyclohexylamine from aniline, 4-methyl-cyclohexylamine (4-MCYA) from /Holuidine. and 4-feri-butylcyclohexylamine (4-tBuCYA) from 4-tert-butylaniline. At 50 % conversion the cis trans ratio of 4-MCYA was 2, while tBuCYA it was 1.6.

The effect of catalyst pore size on the hydrogenation of 4-tert-butylaniline was examined using catalysts M1081, M1272, M1079, and M1273. The effect on the rate is shown in Table 2.

This paper examines the hydrogenation of aniline, /Moluidinc. and 4-fcrt-butylanilinc over a series of 2.5 % Rh/Si02 catalysts, comparing reaction rates and product selectivities. Further studies concentrated on examining support particle size and average metal crystallite size effects on /Moluidinc hydrogenation and the support pore size effects on 4-tert-butylaniline hydrogenation. 

Aniline (0.0196 moles, Sigma-Aldrich), /Moluidinc (0.0196 moles, Sigma-Aldrich) or 4-tert-butylaniline (0.0196 moles, Sigma-Aldrich), was dissolved in 50 ml of 2,2,4-trimethylpentane in a conical flask (the flask was heated gently to 323 K to aid dissolution of /Moluidinc).

The redox noninnocence of the 2-mercapto-3,5-di-tert-butylaniline ligand has recently been investigated with nF ions. The spectroelectrochemistry of the complex displays a range of electron transfers where the monocation, the neutral species, and the mono- and dianions have been characterized. In a related manner, Wieghardt and coworkers have reported the first example of a stable N, O-coordinated o-iminobenzoquinone via air oxidation of the initial nF complex with 2-anilino-4,6-di-tert-butylphenol (94). The analogous o-iminobenzosemiquinonate 7r-radical complex was also isolated for this system and earlier for the bis-(o-immobenzosemiquinonate)nickel(II) complex. ...

Aromatic primary amines react with lead tetraacetate to give symmetrical azo compounds in varying yields, via hydrazo intermediates." " However, in the case of 2,4,6-tri-tert-butylaniline, reaction with lead tetraacetate in benzene at 5°C led to a mixture of three products, the formation of which can be explained by a ligand coupling process. (Scheme 7.2)...
