Abstract

These tetrasilylethylenes are sterically very crowded and show interesting properties; for example, an X-ray crystallographic study on tetrakis (trimethylsily1) ethylene (2a, R= Me) reveals that the double bond of 2a is twisted by 29.5. 2c An obvious approach to more congested olefins involves the reaction of 1 with a bulky alkylating reagent.
