A
samarium-promoted synthesis of (
E)-nitroalkenes from1-bromo-1-nitroalkan-2-ols in high yields and with totalselectivity is reported. This reaction together with the easyand efficient preparation of the 1-bromo-1-nitroalkan-2-olsconstitutes a simple and advantageous alternative towardnitroalkenes with total
E-stereoselectivity. A mechanism isproposed to explain the
E-stereoselectivity of the
-elimination reaction.
