An efficient microwave processing has been developed for the synthesis of metal phthalocyanines (MPc: M=Cu, Mn, Al, Co and Zn) through the condensation reaction of phthalic anhydride and urea with various metal chlorides in the presence of ammonium molybdate catalyst under solvent-free condition using microwaves, as a green chemistry procedure. It was demonstrated that microwave processing combined with solvent-free techniques leads to shorter reaction times, higher yields, cleaner reaction products and easier work-up than classical processing. The products synthesized at various temperature, time and kind of metal have been analyzed by means of X-ray diffractometry(XRD) and scanning electron microscopy(SEM).
