Investigations on organo‐tin compounds. VII the addition of organo‐tin hydrides to olefinic double bonds

A new method for the synthesis of tin‐carbon bonds is described. The synthesis involves the non‐catalysed addition of organo‐tin hydrides to olefinic double bonds at moderate temperatures (60–100°). This method allows the preparation of a variety of hitherto unknown types of functionally substituted organo‐tin compounds, of which typical representatives are described. The structure of the addition products is discussed briefly. It has been shown that the addition of organo‐tin hydrides to olefins does not follow the rule of Markownikow. In a few cases a deviation from the expected addition reaction was observed. Examples of such anomalous reactions are given.
