We describe the preparation of trifluorovinyllithium (from chlorotrifluoroethylene in ether) and of (E)- and (Z)-1,2 difluorovinyllithiums. These reagents present useful synthons on the way to α,β-difluoro-α,β-unsaturated alcohols and acids as either (E)- or (Z)-isomers, and to β,γ (or γ, δ)-difluoro β,γ(or γ,δ)-unsaturated alcohols.
我们描述了三氟乙烯基锂的制备(来自氯三氟乙烯在醚中)以及(E)-和(Z)-1,2-二氟乙烯基锂的制备。这些试剂是合成α,β-二氟-α,β-不饱和醇和酸(作为(E)或(Z)异构体)以及β,γ(或γ,δ)-二氟β,γ(或γ,δ)-不饱和醇的有用合成中间体。
