  摘要：

  甲硫基和甲基磺酰基噻吩可通过正丁基锂和超碱（LICKOR）一步一步进行多金属化。2-（甲硫基）噻吩在5中和在α与甲硫基硫原子上被双金属双金属化。3-（甲硫基）噻吩被有机锂在2和5位上双金属化，并在这两个位置被三金属化，并通过超碱在硫醚醚硫原子的α处被三金属化。3-（甲基磺酰基）噻吩通过有机锂在2中和在磺酰基硫原子的α中被双金属化，而2-（甲基磺酰基）噻吩在相同条件下进行降解。

  The invention provides a method of preparing regioregular HT poly(3-substituted-thiophene). The method includes contacting a 3-substituted-thiophene-metal complex with a manganese(II) halide to provide a 3-substituted-thiophene-manganese complex; and contacting the thiophene-manganese complex with a nickel(II) catalyst to provide the regioregular HT poly(3-substituted-thiophene). The substitution at the 3-position can be a variety of different groups. Additionally, unsubstituted and 3,4-disubstituted polythiophenes can also be prepared by the method. Electronic devices can be made using the polymers prepared as described herein.

  Methods of preparing conducting polymers and the conductive polymers prepared therefrom are provided. Electronic devices can be made using the polymers prepared as described herein. A method of preparing a conducting polymer is disclosed comprising: combining a di(C 2 -C 12 )alkyl metal reagent together with a first dihalo-monomer and an optional second dihalo-monomer to form a monomer-metal complex; and combining the monomer-metal complex together with a metal catalyst to provide the conducting polymer, wherein each dihalo-monomer is independently an aromatic or heteroaromatic group substituted by two halogens wherein the halogens are the same or different.
