Synthesis of 2-Thio-Δ4-Thiazolines as Possible Fungicides

Department of Chemistry, Ravenshaw College, Cuttack Manuscript received 6 March 1972; revised 11 July 1972; accepted 7 May 1973 Seven ammonium dithio-carbamates prepared from aniline, \(p\)-toluidine, \(p\)-chloroaniline, p­bromoardline, \(p\)-iodoaniline, α-naphthylarnine and β-naphthylainine have been condensed with twelve different (aliphatic, aromatic and alicyclic) ketones, both saturated and unsaturated, in the presence of bromine to yield 2-thio-3,4,5-substituted-Δ4-thiazolines. These thiazolines have been assayed for their fungicidial activity and an attempt has been made to establish a relation­ship between fungicidal activity and chemical structur
