F'uryl-and thienylacrylates (8-14) and acrylic acids (&,I@-14a) are prepared in moderate yields by palladium catalysed coupling of substituted bromofurans and bromothiophenes with ethyl acrvlate.

Abstract The electron impact mass spectra of some benzo[1,2‐b:4,5‐b′]dithiophene‐2,6‐dicarboxylic acid dianilides and dithieno[3,2‐b:2′,3′‐d]thiophene‐2,6‐dicarboxylk acid dianilides are discussed. Dominant peaks in these dianilides are formed by the cleavage of a CN bond on one side of an anilino group. These ions fragment further by the cleavage of a CC bond on the other side of an anilino group and a CONRPhR′ group may be lost directly. After loss of CO, the characteristic benzodithiophene ...

Abstract Mass spectra of fourteen 2‐styryl‐ and 2,5‐distyrylfuran and ‐thiophene derivatives are reported. Each styryl substituent has an α‐carboxylic acid or methyl carboxylate substituent. Although the parent ion is the base peak for the styryl and distyryl derivatives, the distyryl species showed less fragmentation than the styryl species. In addition to simple bond cleavages, loss of formic acid or methyl formate was important in many of the species, presumably forming acetylenic fragments.
