formation of the complexes [Pt(dppe)SC(NHR)2}2](PF6)2 (1a, R=H; 1b, R=Me; 1c, R=Et). In contrast, the reaction of [PtCl2(dppe)] with one equivalent of the potentially bidentate thiosemicarbazides NHRC(S)NHNR′2 (R=Me, R′=H; R=Et, R′=H; R=Ph, R′=H; R=Me, R′=Me) in the presence of NH4PF6 led to substitution of only one chloride and formation of the complexes [PtCl(dppe)SC(NHR)NHNR2′-S}](PF6) (2a, R=Me, R′=H;
The invention relates to thiazolidine derivatives having in 4-position a hydroxy group and a 3'-sulphamyl-phenyl substituent, in 2-position an imino group and in 1-position an aliphatic or cycloaliphatic substituent. Said thiazolidines have diuretic activity. The invention also relates to a process for the manufacture of said compounds.
