A new solid base catalyst in microwave assisted organic chemistry is proposed. Successful replacement of sodium hydride by environmentally friendly polyaniline based catalyst is achieved to convert iminodithiazoles into aryl isothiocyanates and quinazolines under microwaves. The simple ha nding, reusability and possibility of "dry media" microwave processes represent the main advantages of polyaniline based catalyst.
