Iron (11) complexes with N-su bstituted bidentate and tetradentate thiosalicylideneimines can be prepared by the reaction of bis(thiosalicylaldehydato)iron(ll) with appropriate primary amines. The bidentate compounds show S = 2 spin states while a number of the tetradentate compounds have the unusual S = 1 state. The tetradentate complexes react with CO to form monocarbonyl complexes and with O2 to form Fell' p-0x0-bridged derivatives. Some evidence is presented to support the preliminary formation at l o w temperatures of a dinuclear iron(iii) peroxo-species as the precursor of the p-0x0-compounds. Several spin-paired Fell1 compounds containing SN2-bonded tridentate ligands are also reported.

“…Although t- Bu sulfides proved to be perfectly resistant to the strong basic reaction conditions involved in these standard methods, the thioester group would have been cleaved. The presence of free thiols also would not have been possible, since they react with aldehydes leading to polymeric material …”

Novel Synthesis of Protected Thiol End-Capped Stilbenes and Oligo(phenylenevinylene)s (OPVs)

et al. 2003

View full text Add to dashboard Cite

The first general procedures for preparation of thiol end-capped stilbenes and oligo(phenylenevinylene)s (OPVs) with tert-butyl- and acetyl-protected thiol termini have been developed. These reactions proceed via Br/Li exchange, McMurry, and Wittig-type reactions. The thiol functionality is protected against strong basic and acidic reaction conditions as a t-Bu sulfide. As a key point in the method, reprotection of the thiol group is accomplished by means of acetyl chloride and boron tribromide. The novel strategy forms the basis for stepwise introduction of 4-mercaptostyryl units in OPVs. The new mono-, di-, and trimercapto OPVs have potential applications as one, two, and three terminal molecular devices in gold nanoparticle clusters, self-assembled monolayers, and optoelectronic devices.

“…As a result, a huge amount of literature has been accumulated on quinoline synthesis. 13 The early syntheses of quinoline derivatives, such as the Friedländer, 13a b Skraup, 13c Doebner, 13d Combes, 13e Conrad–Limpach, 13f g and Povarov 13h i synthesis, generally relied on aniline or aniline derivatives as starting materials along with diverse annulation partners. With time and advanced synthetic techniques, several elegant methods have been developed for quinoline synthesis.…”

Synthesis of Quinoline and Quinolin-2(1H)-one Derivatives via Nickel Boride Promoted Reductive Cyclization

et al. 2023

View full text Add to dashboard Cite

A mild and efficient approach for the synthesis of diversely substituted quinoline and quinoline-2-one derivatives has been disclosed. In situ-generated nickel boride was proved to be an effective promoter of the reductive cyclization reaction. Broad substrate scope, mild reaction condition, consistent yield and wide range of functional group tolerance are the other notable features of the newly discovered reaction. A large number of quinoline and quinoline -2-one derivatives may be prepared from milligram to multigram scale employing this intramolecular reductive cyclization protocol.
