Effective syntheses of 2-trimethylsilylmethyl-3-trimethylsilyl-1-propene and its 1,1-d2- and 1,1,1',1',3,3- d6-isotopomers

摘要

New 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.
