The present invention relates to a process to prepare fluoroform (CHF3), notably radio labelled with fluorine-18, comprising a substitution reaction between CHAF2 and a fluoride salt,
wherein A represents
or
as well as a process to prepare a composition comprising copper-based or silver-based trifluoromethylated reagents using notably the fluoroform thus prepared and the use of a composition comprising copper-based trifluoromethylated reagents or a mixture comprising a copper salt and a composition comprising silver-based trifluoromethylated reagents as a trifluoromethylating agent, notably radio labelled with fluorine-18.
本发明涉及一种制备氟甲烷(CHF3)的方法,特别是用氟-18进行放射标记,包括CHAF2和氟化物盐之间的取代反应,其中A代表或,以及制备含铜或含银三氟甲基试剂的方法,特别是使用制备的氟甲烷,以及将含铜三氟甲基试剂或包含铜盐和含银三氟甲基试剂的混合物作为三氟甲基化试剂的用途,特别是用氟-18进行放射标记。
