The (Sn(PC)Cl/sub 2/) catalysts were evaluated in the homogeneous and heterogeneous form. The results obtained for various amounts of (Sn(PC)Cl/sub 2/) under standard conditions are listed. The % conversion given is the average of at least three runs and reproducibility is +-3%. The dependence of the conversion on the amount (mg) of the (Sn(PC)Cl/sub 2/) catalyst is shown. It is seen that, as the amount of catalyst increases, the conversion increases linearly at 200/sup 0/C but appears to be leveling off with higher amounts of catalyst at 250/sup 0/C. In every case, however, the conversion is higher at 250/sup 0/C than at 200/sup 0/C. In these experiments less than 10% of the catalysts are recovered at 200/sup 0/C and only traces at 250/sup 0/C. Further, the reaction solution is only slightly colored green-blue indicating that the catalysts are being largely destroyed during the reaction, i.e., there is an irreversible reduction of the phthalocyanine ring. The ir spectra of the recovered catalyst shows bands characteristic of (Sn(PC)Cl/sub 2/). The results for the supported catalysts, (Sn(PC)Cl/sub 2/)/SiO/sub 2/, are listed. Again, the % conversion is the average of triplicate runs and reproducibility is +-3%. The dependence of the conversion on catalyst loading level is shown. It is seen that, as the loading level increases, the conversion increases with a leveling off for the 250/sup 0/C runs. In every case however, the conversion is higher at 250/sup 0/C than at 200/sup 0/C. The supported catalysts can be recovered.
