Abstract
AbstractNew and effective routes to synthesize 2‐trimethylsilylmethyl‐3‐trimethylsilyl‐1‐propene and its 1,1‐d2‐ and 1,1,1′,1′,3,3‐d6‐isotopomers have been developed, using the displacement reaction of lithium trimethylsilylcyanocuprate with allylic halides and tosylates. These compounds are pivotal precursors for the gas‐phase synthesis and characterization of the trimethylenemethane anion, and for negative ion photoelectron spectroscopic investigations of the singlet–triplet splitting in trimethylenemethane.
