The sila-allyl anion is an allyl anion in which one of the carbon atoms is replaced with a silicon atom. The synthesis of a stericall hindered derivative will enable us to investigate the resonance stabilization of the sila-allyl system. One method for obtaining this information will be analysis of the variable temperature NMR spectrum of the system to obtain rotational barriers. Our progress on the synthesis of a silaallyl anion will be presented as well as our efforts to improve the synthesis of the tris(trimethylsilyl)vinylsilane and the reactions of it to form the anion.
