TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Compound: The copper salt is copper chloride or copper cyanide.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preparation (claimed): A silicon-containing compound of formula (a) is reacted with metal-containing compound of formula (b) in presence of copper salt, to obtain a thiophene-containing compound of formula (c). The obtained compound (c) is aromatized in presence of dehydrogenation agent, to obtain a thiophene derivative (I).X=halo;M=transition metal of group IV-VI of periodic table, preferably titanium, zirconium or hafnium;andL1,L2=delocalization cyclic ( eta )-coordination-type ligand. Preferred Definitions:    R1,R3-R6,R8=H, or 1-20C alkyl, 2-20C alkenyl, 6-20C aryl or 6-20C alkynyl (all optionally substituted);    R2,R7=H;    A1,A2=-C=C-, -CC- or bivalent aromatic ring;    m=1;and    R11,R12=trimethylsilyl.    EXAMPLE - Bis(cyclopentadienyl)zirconium dichloride (in mg) (351), 1.57M hexane solution (1.53 mL) of n-butyllithium, 1,2-bis(3-phenyl-2-propynyl)-3,4,5,6-tetrapropyl benzene (475), cuprous chloride (196), 1,3-dimethyl-3,4,5,6-tetrahydro-2(1H)-pyrimidinone (DMPU) (0.44 mL) and 2,5-bis(trimethyl silylethynyl)-3,4-diiodothiophene (634) were added and mixed, to obtain 4,11-diphenyl-6,7,8,9-tetrapropyl-1,3-bis(trimethylsilylethynyl)-5,10-dihydroanthra(2,3-c)thiophene (359). The obtained 4,11-diphenyl-6,7,8,9-tetrapropyl-1,3-bis(trimethylsilylethynyl)-5,10-dihydroanthra(2,3-c)thiophene (108) and 2,3-dichloro-5,6-dicyano-parabenzoquinone (98) were added to toluene (6 mL) and stirred at room temperature. Then, ( gamma )-terpinene (1.16 mL) and N,N-diiodopropylethylamine (147 mu l) were added, and the mixture was heated at 110 degrees C and stirred for 3 hours. The resulting mixture was cooled to room temperature, and the liquid layer was vacuum-dried. The residue was purified using hexane and toluene (10:1) with alumina chromatography, and further washed and vacuum-dried using methanol, to obtain 4,11-diphenyl-6,7,8,9-tetrapropyl-1,3-bis(trimethylsilylethynyl)anthra(2,3-c)thiophene (88) having yield of 82%.
