Reductive alkylations involving 2°- and 3°-enolyl adduct radicals
摘要:
Reductive tert-butylation of electronegatively substituted alkenes is readily achieved in Me(2)SO by reaction with excess t-BuHgCl/Et(3)SiH. Reactivity studies indicate that towards t-Bu. s-cis enones are more reactive than the s-trans conformers.
