Organosilicon 1,2-anionic rearrangements

Anionic Rearrangement of Organosilicon and Germanium Compounds, 16, 1 Applications of 9mSn Mossbauer Spectroscopy to the Study of Organotin Compounds,... 

In 1964 it was discovered that organosilicon groups migrate from one nitrogen atom to the other in anions of silicon-substituted hydrazines /, 20). Subsequent investigations established that the anionic rearrangement of organosilyl hydrazines takes place with unprecedented speed. 

The hydrazine rearrangement was the first known anionic rearrangement of organosilicon compounds and has been studied more thoroughly than any other. A previous review, now somewhat out-of-date (24), covered the early experimental results on this reaction. 

As future developments take place in the study of anionic rearrangements, the exceptionally mobile organosilicon and other organometallic migrating groups seem likely to be of crucial and increasing importance.

As for the rearrangements of organosilicon compounds, there are anionic rearrangements, rearrangements of methylpolysilanes, radical rearrangements, a-carbonium ion rearrangements, etc. [14].
