Catalyzed liquid phase fluorination of 1230za
摘要:
A liquid phase process is provided for the preparation of 1233zd with reduced oligomer formation via the fluorination of 1230za with HF in the presence of a catalyst selected from TFA and triflic acid. The 1233zd is a known intermediate useful for preparing 245fa.
