Mass spectral fragmentation patterns of some new 3,7-dichloro-benzo[1,2-b:4,5-b′]dithiophene-2,6-dicarboxylic acid dianilides and 3,5-dichloro-dithieno[3,2-b:2′,3′-d]thiophene-2,6-dicarboxylic acid dianilides. II
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. Th...

| description | 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 radical cation, C10H2S2Cl 2□ +., at m/z 256 and the dithienothiophene radical cation, C8S3Cl 2□ +., at m/z 262 are formed from their respective precursor compounds. |
