Disperse dyes based on aminothiophenes: Their dyeing applications on polyester fabrics and their antimicrobial activity

A series of monoazo disperse dyes derived from arylazothienopyridazines were synthesized. Fastness properties of dyed polyester samples were measured. Most of the dyed fabrics tested displayed excellent washing and perspiration fastness and moderate light

Studies with condensed aminothiophenes: Microwave assisted cycloaddition reactions of thieno[3,4-d]-pyridazinone and thieno[3,4-c]quinolinone

The arylformazane (2) was produced via coupling the α-oxoarylhydrazones (1) with aromatic diazonium salts. These formazane condensed readily with ethyl cyanoacetate to yield arylazopyridazinones (4) that reacted with sulphur in the presence of piperidine
