A novel series of tripodal ligands with thiophenylether arms connected to an anchoring nitrogen has been investigated. Seven tripodal ligands were synthesized by combining methyl, isopropyl, and tert-butyl residue bearing thiophenylether sites as groups w

A short route for the preparation of tetradentate amine-thioether and amine-thiolate ligands derived from thiosalen is reported. The ligating properties of several of the synthesized ligands towards Ni(II) has been examined. The diamine-dithiophenolate li
Nickel-catalysed Substitutions of Aryl tert-Butyl Sulfones with Organometallic Reagents: Synthesis of ortho-Substituted Unsymmetrical Biaryls

In the presence of a catalytic amount of a nickel salt, aryl tert-butyl sulfones react with aryl Grignard reagents to give biaryls.This reaction is used in conjunction with the powerful ortho-lithiation-directing ability of aryl tert-butyl sulfonyl groups to make unsymmetrical ortho-substituted biaryls.In certain cases, the substitution of an aryl alkylsulfonyl group by an organometallic reagent is possible without a transition metal catalyst.
α',α'-DISILYLATED TERTIARY BENZAMIDES AS DUAL ORTHO- AND α'-CARBANION SYNTHONS. AMIDE PETERSON OLEFINATION ROUTES TO N-BENZOYL ENAMINES, ISOQUINOLINES, AND DIBENZAZOCINES

α',α'-Disilylated benzamides 2, prepared by LiTMP/TMSCl in situ trap procedure, constitute ortho- and α'-carbanion synthons which provide N-benzoyl enamines (5), isoquinolines (6), dibenzoazocines (9) by Peterson olefination, and pyrroles (11) by cycloaddition.The conversion of 2 into other useful functionality is described.
