Reaction of Magnesium Alkylidene Carbenoids with Lithium Acetylides and LithThiolates: A Novel Synthesis of Conjugated Enynes and Vinyl Sulfides. —
36- 052 ium
Magnesium alkylidene carbenoids, generated in situ, react with lithium acetylides or
lithium thiolates to give the corresponding conjugated enynes and vinyl sulfides, respectively. The intermediate of the reaction is an alkenyl anion which can be trapped
with electrophiles like iodide, aldehydes and acyl chlorides. — (WATANABE, M.;
