Syntheses and bioactivities of mixed butyl/cyclohexyl tin carboxylates

Eight novel compounds have been synthesized and they are two series of mixed tri(butyl/cyclohexyl) tin carboxylates:Bu_nCy_(3-n) SnO_2CR (n=1,2;R=n-C_3H_7,C_6H_5,4-ClC_6H_4,4-NO_2C_6H_4).Inaddition to the studies of their structures with IR,~(119)Sn and ~(13)C NMR,we tested their fungicidal,insec-ticidal and acaricidal activities.The percentage of inhibition to the aforementioned phytopathogen isabout 80—100% at 50 ppm in glasshouse and 100% for T.Uriticae at 500 ppm.Those findingsindicate that this kindof compounds have both fungicidal and acaricidal activities and mayhave a goodprospect for applications.

Eight novel compounds have been synthesized and they are two series of mixed tri(butyl/cyclohexyl) tin carboxylates: Bu_nCy_3-n SnO₂CR (n = 1, 2; R = n-C₃H₇, C₆H₅, 4-ClC₆H₄, 4-NO₂C₄H₄). In addition to the studies of their structures with IR, ¹¹⁹Sn and ¹³C NMR, we tested their fungicidal, insecticidal and acaricidal activities. The percentage of inhibition to the aforementioned phytopathogen is about 80—100% at 50 ppm in glasshouse and 100% for T. Uriticae at 500 ppm. Those findings indicate that this kind of compounds have both fungicidal and acaricidal activities and may have a good prospect for applications.
