The reactions of silver(I) with 1,4,7,11-tetraazacyclotetradecane (isocyclam), 1,4,8,11-tetraazacyclotetradecane (cyclam) and 1,4,8,12-tetraazacyclopentadecane ((15)aneN{sub 4}) resulted in the production of silver and a silver(II) tetraaza macrocyclic complex, AgL{sup 2+}. 2Ag{sup 1+} + L {yields} AgL{sup 2+} + Ag. The mechanisms of these reactions involve the formation of AgL{sup 1+} which is oxidized by silver(I) to Ag and AgL{sup 2+}. However, the reaction of 1,4,7,10-tetraazacyclododecane ((12)aneN{sub 4}) with silver(I) resulted in the formation of an unstable complex. Silver(I) did not react with 1,4,7,10-tetrabenzyl-1,4,7,10-tetraazacyclododecane. The most stable Ag(II) complex in aqueous solution with regards to decomposition contains the (15)aneN{sub 4} ligand, while the Ag(II) complex containing (12)aneN{sub 4} is the least stable. Attempts to oxidize benzyl alcohol to benzyl aldehyde using (Ag(cyclam))(ClO{sub 4}){sub 2} were unsuccessful.
