Seventeen tris(2-methyl-2-phenyl propyl)tin aryloxyacetates were synth
esized by the reaction of corresponding aryloxyacetic acids and tris (
2-methyl-2-phenyl propyl) tin hydroxide, The IR, H-1 NMR and C-13 NMR
spectra of these compounds were studied, The data of IR indicate that
these compounds are four-coodinated monomeric organotin compounds, The
se compounds have a good acaricidal activity.
