2. The inductive effect drops across every sigma bond involved limiting its effect to only a few bonds.
3. Anchimeric assistance of the sigma bond between carbons 1 and 6 was rationalized as the explanation for this kinetic effect.
4. For there to be a constructive sigma bond formed after the shift, the reaction would have to be suprafacial.
5. In these compounds the central bond consists only of pi bonding because of a sigma antibond accompanying the sigma bond itself.
6. Silicon can form sigma bonds to other silicon atoms ( and disilane is the parent of this class of compounds ).
