Abstract: Seventeen derivatives of mixed trialkyltin carboxylates with the formula (PhMe2SiCH2)Cy2SnO2CR have been synthesised.The results of IR NMR(1H,13C,119Sn) and MS showed that this kind of compounds is four-coordinated and that there are two good linear relationships between the δ 119Sn and Hammett constants of para-substitutent of the corresponding aryloxy-acetates and arylcarboxylates.These compounds have a good acaricidal activity in the preliminary bioassay tests.

Key words: Mixed trialkyltin, Organotin, Organosilicon, Carboxylate, Cyclohexyl
