PTA l,3,5-triaza-7-phospha-adamantane

Triruthenium complexes bridged by l,r-bis(diphenylphosphino)ferrocene, thus formally containing Ru-P-C bonds, have been reported. " Examples are complexes Ru3(CO)i2-2 L ( =1, 2). Phosphine-substituted complexes, such as Ru3(CO)9(PTA)3 (PTA= l,3,5-triaza-7-phospha-adamantane), are soluble in water. Finally, triruthenium complexes, substituted with quinolines, react with dppm, forming clusters with Ru-C-P bonds due to the orthometallation of the dppm phenyls. " ...
