Highly versatile: The Ruppert–Prakash reagent (Me₃SiCF₃) can be an efficient source of difluorocarbene. By varying the nonmetallic initiator that is used (F⁻ at lower temperatures and I⁻ at higher temperatures), a range of structurally diverse alkenes and alkynes can be converted into the corresponding gem‐difluorinated cyclopropanes and cyclopropenes in good yields (see scheme).

宝石二氟环丙烷和环丙烯的合成：以三氟甲基三甲基硅烷为二氟卡宾来源

用途广泛：Ruppert–Prakash试剂（Me ₃ SiCF ₃）可以是二氟卡宾的有效来源。通过改变所使用的非金属引发剂（F ^-在较低温度和我^-在更高的温度），范围结构多样的烯烃和炔烃的可转化成相应的宝石-difluorinated以良好产率和环丙烷环丙烯（参见方案）。
