- SYNTHESIS OF EXTENDED ACYCLIC AZATHIENES WITH AROMATIC SUBSTITUENTS. III. PHTHALIMIDO GROUP AS THE LEAVING GROUP
-
The use of the phthalimido group as the leaving group makes it possible to obtain asymmetric 1,7-diaryl-1,3,5,7-tetraaza-2,4,6-trithia-1,2,5,6-heptatetraenes, which are not obtainable by the previously known methods.Cesium fluoride in acetonitrile increases the nucleophilicity of the nitrogen atom of the N-trimethylsilyl derivatives of acyclic azathienes and phthalimide.In acetonitrile solution a spontaneous shortening of the sulfur-nitrogen chain of 1,7-bis(trimethylsilyl)-1,3,5,7-tetraaza-2,4,6-trithia-1,2,5,6-heptatetraene takes place.
