α-lithio α-trimethylsilyl cyclopropanes have been prepared by two different routes. They have been tested as precursors of alkylidene cyclopropanes, cyclopropylidienes and α-silyl α-vinyl cyclopropanes.

The Z and E teomers of the title compounds are regioselectivity and stereoselectively prepared respectively by reaction of phosphorus ylides with α-selenocyclopropyl aldehydes and by addition of α-lithio seleno-cyclopropanes on α-seleno aldehydes.
