## Stable isotope-labelled tetra-n-butyl(l24)tin was fxnthesized by the reaction of n-butylmagnesium bromide with 4SnC14. Tri-n-butyltin bromide was synthesized by bromine cleavage of the tetraalkyltin. The compound can be used to trace chemical, biological and physical processes in environmental

The oral acute toxicity for tri-n-butyltin glycocholate (TBT-GA), a newly synthesized organotin steroid, was determined using Long Evans rats. The compound was suspended in corn oil and adminstered by gavage using standard techniques. Unlike tri-n-butyltin taurocholate, which exhibited two different
The kinetics and absolute rate constants for the free-radical chain reaction of tri-nbutyltin hydride with di-t-butyl disulfide have been measured in cyclohexane at 30". The rate controlling step for chain propagation involves the cleavage of the disulfide bond by an attacking tributyltin radical. T
## Abstract Rate constants for the triβ__n__βbutyltin radical (**Sn Β·**) induced decomposition of a number of peroxides have been measured in benzene at 10Β°C. The values range from βΌ100 __M__^β1^ sec^β1^ for diβ__t__βbutyl peroxide to 2.6 Γ 10^7^ __M__^β1^ sec^β1^ for diβ__t__βbutyl diperoxyisophth
