Abstract: The invention pertains to thiophenes of the formula (I), where n is 2 to 6; L and L are hydrogen, optionally substituted C1-C10 alkyl, C3-C7 cycloalkyl or phenyl, or L and L together with the connecting nitrogen atom represent a heterocyclic radical; X and Y are hydrogen, optionally substituted C1-C10 alkyl, C3-C7 cycloalkyl or phenyl; and Z is cyano, hydroxysulfonyl, C1-C10 alkoxycarbonyl, optionally substituted C1-C4 alkylsulfonyl, optionally substituted phenylsulfonyl or a radical of the formula (a), where R is hydrogen or cyano and R and R are cyano, nitro, C1-C10 alkoxycarbonyl, optionally substituted C1-C4 alkylsulfonyl or optionally substituted phenylsulfonyl. The invention also relates to the use of said thiophenes in nonlinear optics, a method for the preparation of bithiophenes, and stannylthiophenes as their intermediates.

Abstract: Cpds. of formula (I): (where each of R1 and R2 is H or halogen, Me is methyl and R1 can also be an aliphatic gp.) are prepd. by reacting a cpd. (II) with a cpd. (III): (where X is halogen) in the presence of =10 wt.% FeCl3, based on (III), as Friedel-Crafts catalyst. (I) are intermediates for dyes and pesticides.

Abstract: Aromatic ketones are prepd. by reacting a ring-acylatable aromatic cpd. with an aromatic carboxylic acid chloride or anhydride (I) in the presence of =10 wt.% FeCl3, based on (I) as Friedel-Crafts catalyst. The use of such small amts. of catalyst reduces sec. chlorination and oxidn. reactions and facilitates sepn. and recovery of the catalyst. The prods. are inters. for dyes and pesticides.

Abstract: Aromatic ketones, (I) are prepd. by acylating an aromatic ring-acetylatable aromatic cpd., (II), with the mixed anhydride, (II) of a carboxylic acid and of a dihalophosphoric acid, in the absence of catalytic Friedel-Crafts catalyst proportions. Aglation is pref. at 0-100(0-60)degrees C opt. in inert solvent. (I) are dye- and pesticide-intermediates. Pure (I) can be prepd. in high yields. Friedel-Crafts catalyst absence obviates catalyst sepn. and waste water pollution.
