The chemistry of some di- and tri-phenylmethane dyes. Stephen A. Gorman Two series of dyes have been prepared: a comprehensive series of novel, unsymmetrical Malachite Green type dyes containing different amino substituents in the 4-positions of the phenyl rings and a series of symmetrical Michier's Hydrol Blue type dyes.

Hexacyanidometalate molecular chemistry: di-, tri-, tetra-, penta- (cis/trans) and hepta-nuclear chromium–copper and cobalt–copper complexes† Maria Hernandez-Molina , a Jérôme Long , a Lise-Marie Chamoreau , a Jean-Louis Cantin , b Jürgen von Bardeleben b and Valérie Marvaud * a Not sure if you care, but the uni-, di-, and tri-, etc, work into the complex molecule nomenclature, to designate how many side groups of a particular type are on a chain. For instance, 18-bromo-12-butyl-11-chloro-4,8-diethyl-5-hydroxy-15-methoxytricos-6,13-dien-19-yne-3,9-dione has two ethyl groups, two double carbon bonds, and two oxygen molecules. The present study describes a series of pentafluorobenzyl ammonium salts with two, three, or four C6F5 units in order to investigate simultaneous interactions of several perfluorinated arenes with anions in the crystalline state. Most of the structures show multiple anion−π contacts. However, only 6·2HI reveals an effective encapsulation of the iodide ion by the aromatic units.

Because of the specific physico-chemical properties of the fluorine atom, fluorinated compounds play an important key role in drug A large number of chemical derivatives with 1,4-benzoquinone as the basic subunit reported a convenient high yield synthesis of 2,6-di-t-butyl-1,4- benzoquinone of 2,4,6-tri-t-butyl phenol (98) with t-butylhydroperoxide (TBHP) (Sc When two or more identical substituents are present in a molecule, a numerical prefix (di, tri, tetra etc.) is used to designate their number.
