✦ Synopsis

Allyiic tri-n-butyltins can be prepared easily by the treatment of allylic sulfones or sulfides with tri-n-butyltin formate in refluxing xylene.

Tri-n-butyltin hydride has often been employed for the synthesis of allylic 1) or vinylic tri-n-butyltins which are useful for allylating or vinylating reagentso3;) 2a) However, the hydride is not only unstable thermally but also unstable

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 tri‐__n__‐butyltin radical (**Sn Β·**) induced decomposition of a number of peroxides have been measured in benzene at 10Β°C. The values range from ∼100 __M__^βˆ’1^ sec^βˆ’1^ for di‐__t__‐butyl peroxide to 2.6 Γ— 10^7^ __M__^βˆ’1^ sec^βˆ’1^ for di‐__t__‐butyl diperoxyisophth
