Addition reactions to disilenes

Nevertheless, mechanistic investigations on the addition reaction to disilenes and silenes advanced considerably in recent years. In this chapter, the author tries to survey the progress achieved recently. The author will not try to review all aspects of the chemistry of silicon unsaturated species since many extensive reviews on this topic are already available6-12. 

These E-Z isomerization studies of disilenes indicate that the n overlap between two 3p orbitals of silicon is sufficiently effective to retain the configuration around the double bond, although the 7r bonding of disilenes is significantly weaker than that of the C=C double bond. Therefore, it is expected that if appropriately substituted disilenes can be generated, regiochemistry as well as diastereochemistry of addition reactions to disilenes can be investigated even with transient reactive disilenes.
