Page/Page column 22-23, (2008/06/13)
The present invention is related to a new synthesis for preparing para-phenyl alkynyl benzaldehyde of general formula (I). The compounds of formula (I) are useful building blocks, in particular in the synthesis of electrically conducting polymers. R is selected from the group consisting of C1-C12-alkyl, C1-C12-alkyl aryl, C1-C12-alkyl heteroaryl, C2-C12-alkenyl, C2-C12-alkenyl aryl, C2-C12-alkenyl heteroaryl, C2-C12--alkynyl, C2-C12-alkynyl aryl, C2-C12-alkynyl heteroaryl, C3-C8-cycloalkylC1-C12--alkyl-C3-C8-cycloalkyl, C1-C12-alkoxy, aryl, heteroaryl, halides.
