Novel fluorescent N,O-chelated fluorine-boron benzamide complexes containing thiadiazoles: Synthesis and fluorescence characteristics

A series of N-(5-phenyl-1,3,4-thiadiazol-2-yl)benzamide derivatives and their corresponding BF2 complexes were synthesized, and their photophysical properties were determined. The effect of the derivatives with various substituents on the benza

New access to pyrazole, oxa(thia)diazole and oxadiazine derivatives

1,4-Disubstituted thiosemicarbazides 1b-f reacted with ethenetetracarbonitrile (5) in dimethylformamide with formation of 2-substituted 5-phenyl-1,3,4-thiadiazoles 2a-f and 2-substituted 5-phenyl-1,3,4-oxadiazoles 4a-f. Upon addition of 5 to 1c-e in chlorobenzene, 3-amino-2-benzoyl-4,5,5- tricyano-2,5-dihydro-1H-pyrazole- 1-[N-(4-tricyanovinyl)phenyl]carbothioamide (12), 5-benzylamino-, and 5-allylamino-4-benzoyl-2,3-dihydro-[1,3,4]thiadiazol- 2,2-dicarbonitrile (13a,b) and 5-amino-1-benzoylpyrazole-3,4-dicarbonitrile (14) as well as 2-phenyl-4H-[1,3,4]-oxadiazine-5,6-dicarbonitrile (15) were formed. Rationales for the role of the solvent and the conversions observed are presented.

Synthesis of 6-Aroylimino-2-aryl-1,3,4-thiadiazolothiadiazolines

Reaction of 2-amino-5-aryl-1,3,4-thiadiazoles (V) with aroyl isothiocyanates gives 2-aroylamino-5-aryl-1,3,4-thiadiazoles (VII) and N-aroyl-N'-(5-aryl-1,3,4-thiadiazol-2-yl)thioureas (VIII).Contrary to earlier reports, cyclisation of VIII in the presence of PCl5 in POCl3 yields 6-aroylimino-2-aryl-1,3,4-thiadiazolo-thiadiazolines (X).Cyclisation of VIII in the presence of other oxidising agents also leads to X.
