O-Aminobenzenethiol

The condensation of o-aminobenzenethiol with pyridine-2,6-dicarbaldehyde does not form the corresponding Schiff base but a polyheterocyclic compound which behaves as a tridentate ligand towards nickel(II).2365 In contrast the reaction of 2-(2-pyridyl)benzothiazoline with nickel(II) results in the opening of the heterocyclic ring and in the formation of a Schiff base ligand which coordinates to nickel(II) as a mononegative tridentate ligand.2366,2367...

Chelate amino complexes (V Y = NH, Z = 0,S) were obtained from [7T-C5H5Co(CO)l2] with o-aminophenols and o-aminobenzenethiols (255). Related complexes are obtained from [Rh(CO)2Cl]2 with the latter ligands... 

Fe3(CO)[2 reacts with o-aminobenzenethiol in boiling cyclohexane to form the nitrogen- and sulfur-bridged complex (XII), through loss of hydrogen from both the sulfur and nitrogen atoms (338). 

The pyrolysis of a number of benzothiazolines, which were prepared by the reaction of o-aminobenzenethiols with ketones, have been investigated by Elderfield and McClenachan . The first-order rate coefficients were estimated by measure-... 

Condensation of o-aminobenzenethiol 547 with 1 in dimethyl sulfoxide gave the phenothiazinone 550 (76JCS(P1)1146, 83S933,... 

Dichloroquinoxaline has been converted into a number of polycyclic derivatives by reaction with o-disubstituted benzenes. Thus reaction with o-phenylenediamines gives tetraazanaphthacenes (17), and the corresponding reaction with 2,3-diaminoquinoxaline gives fluorubin derivatives (18). Quinoxalino[2,3-h]benzothiazine derivatives (19) result from the reaction of dichloroquinoxaline and o-aminobenzenethiol and... 

Cleavage of aryl esters. Aryl acetates, benzoates, pivalates, and tosylates are cleaved under nonhydrolytic conditions (PhSH, K2CO, NMP reflux) alkyl esters are less reactive. o-Aminobenzenethiol is also useful for this purpose. 

The Mn compounds, derived from the terdentate O—N—O or S—N—O donor set Schiff base ligands obtained from the condensation of both substituted " and unsubstituted " o-hydroxyan-iline, anthranilic acid " or o-aminobenzenethiol " with various salicylaldehyde residues, have the...
