Usage

General Description

2,2'-Dimethyl-4,4'-bipyridine, also known as lutidine, belongs to a class of organic compounds known as dialkylpyridines which are aromatic compounds containing two alkyl groups attached to a pyridine ring. It is a colorless liquid with a sharp, offensive smell. Its basic structure is a bipyridine with methyl groups at the 2 and 2' positions. It is used in various chemical reactions due to its properties as a ligand, basically acting as a bridge between two or more central atoms in a molecule, often facilitating or stabilizing certain atomic arrangements. Yet, it should be handled with care because it is a skin, eye, respiratory irritant, and very toxic to aquatic life.

Synthesis of crown-ester-bipyridines and crown-ester-viologens

Six novel 4,4′-bipyridine-crown-esters, derived from [4,4′]bipyridinyl-3,3′-dicarboxylic acid, [4,4′]bipyridinyl-2, 2′-dicarboxylic acid and [4,4′]bipyridinyl-2,2′,6,6′- tetra-carboxylic acid were synthesized employing a procedure closely related to the 'cesium carbonate method'. The 4,4′-bipyridine-crown-esters differ in their substitution positions of the aromatic bipyridine-units, as well as in the geometric extensions of their crown-ester moieties. Addition of 1,3-propane sultone to the 4,4′-bipyridine-crown-esters resulted in five novel propanesultonated 4,4′-bipyridine-crown-ester viologens. Georg Thieme Verlag Stuttgart.

Synthesis of Bipyridyl-, Viologen-, and Quinone-bridged Porphyrins

Mesoporphyrin-II has been bridged by several 2,2'-hydroxymethyl-substituted 4,4'-bipyridine compounds.N-Methylation of the bipyridine bridge groups yielded viologen-bridged porphyrins which have unusual aggregation and fluorescence properties.An improved route to quinone-bridged porphyrins is also reported.
