Thiophene functionalized

The thiophene-functionalized ligand 4-(5-bromothiophene)-2,2 -bipyridine, L, reacts with [Ru(bpy)2Cl2] to give [Ru(bpy)2L] +. The reactivity of the bromo site in coordinated L can be utilized to derivatize (e.g., by Pd(0) coupling) this ligand further. Ligands (85) form the... [Pg.591]

Thiophenes can function either as a diene or as a dienophile in an intramolecular Diels-Alder reaction (90CC405). The 7V-(2-thienyl)allene carboxamide (182) on heating at 130°C leads to (183) by a [4 + 2] cycloaddition in which the thiophene functions as a 4ir component, followed by the usual extrusion of sulfur.

Furthermore, bromothioethenes were reported as fairly useful electrophiles for the coupling reaction with secondary Grignard reagents (Table 5.1, entries 18 and 19) [13]. These transformations occur highly stereo- and chemoselectively at the vinyl bromide moiety whereas the thiophene functionality remains conserved under the described reaction conditions. [Pg.149]

The final stage of the synthesis of thiophene-functionalized fluorenes 121 involved the condensation of lithio derivatives of compounds 120 with the 1,3-dithiolium salt 119, prepared almost quantitatively from 118 by A-methylation (Scheme 9) <1999J(P2)505>. [Pg.975]

Most of the sulfur in immature kerogens of type 11-S is in polysulfide (S-S) functionality (PCLM) whereas in petroleum most of the sulfur is identified in the aromatic thiophene functionality. [Pg.48]

A third concept, utilizing thiophene carboxylic acid esters instead of EDOT derivatives for the construction of PEG-EEXDT block copolymers was disclosed Esterification of 2-thiophene carbonyl chloride with PEG or PEG monoethers yields reactive, thiophene-functionalized PEG blocks, which also can be copolymerized with EEXDT. ...
