HETEROCONJUGATE ADDITION OF LITHIUM ALKYLS TO SUBSTITUTED HETERO-OLEFINS CONJUGATED WITH SULFUR AND SILICON ATOMS

Abstract
Lithium alkyls and a lithiated sulfone carbanion readily added to the substituted hetero-olefins conjugated with silicon and sulfonesulfur atoms among other combination of the third (or fourth) row hetero atoms, e.g. Si, Se and S.
