# Iodine Rearrangements of Tetraallylsilane and Synthesis of Silicon-Stereogenic Organosilanes

## TL;DR

This paper explores how iodine rearranges tetraallylsilane to create silicon-stereogenic organosilanes.

## Contribution

The study introduces a new method for synthesizing silicon-stereogenic organosilanes using iodine.

## Key findings

- Using 1 equivalent of I2 leads to high yields of mono-rearranged products.
- Excess I2 (3 equivalents) causes double rearrangement of tetraallylsilane.
- The process can synthesize valuable silicon-stereogenic organosilanes.

## Abstract

Tetraallylsilane can undergo either a mono or double rearrangement when treated with iodine (I2). The extent of rearrangement depends on the equivalents of I2 used, where 1 equivalent gives high yields of mono-rearranged products and excess (e.g., 3 equivalents) causes double rearrangement to occur. This transformation can be applied to the synthesis of potentially valuable silicon-stereogenic organosilanes.
