Synthesis of some B‐dicarbonyl derivatives of 4‐amino‐3‐thio‐1,2,4‐triazolidine and their use in marine antifouling paints

Abstract

Reaction of 4‐amino‐3‐thio‐1,2,4‐triazolidine with etnyl‐acetoacetate and acetoacetanilide produced 4‐(ethy‐lacetoacetamino)‐3‐thio, 1,2,4‐triazolidine and 4‐(acetoacetanilidamino, ‐3‐thio‐1,2,4‐triazolidine respectively. These were characterised by elemental analysis, 1Rand 1HNMR spectra. Each compound was tested as antifoulant in marine paint formulation in the presence of tributyftin fluoride as a co‐toxin. The antifouling behaviour of the compounds was compared with that of the parent one, 4‐amino‐3‐thio‐1,2,4‐triazalidine and its condensation products with other aromatic and heterocyclic carbonyl derivatives.
