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 le">-elimination reaction.
