A series of metal salts were reacted with aqueous solutions of the tetrasulfonated free base phthalocyanine (H{sub 2}TsPc) in an attempt to prepare the corresponding metal TsPc derivative by direct insertion instead of the usual template reaction in a urea melt. Spectrophotometric analysis showed that Ni{sup 2+}, Cu{sup 2+}, Zn{sup 2+}, Co{sup 2+}, Fe{sup 2+}, Mn{sup 2+}, Pd{sup 2+}, Cd{sup 2+}, and Sn{sup 2+} could be successfully inserted; higher oxidation states as well as Pb{sup 2+} caused precipitation. Reducing species such as Cr{sup 2+} and V{sup 2+} reduced H{sub 2}TsPc but did not insert; Sn{sup 2+} inserted with formation of an air-sensitive intermediate species. Mg{sup 2+}, VO{sup 2+}, Pt{sup 2+}, and Hg{sup 2+} were unreactive. It is recommended that insertion may be the preferable method for synthesis of the MTsPc's listed above when air sensitivity, reaction time, and microscale are important issues in an overall synthetic scheme. 24 refs., 4 figs.
