Abstract:
Disclosed is a process for preparing cis-1,1,1,4,4,4-hexafluoropropene comprising the steps of (a) reacting CCl 4 with a compound having the formula CF 3 CX=CXH, where each X is independently halogen or hydrogen, to form a compound having the formula CF 3 CXClCXHCCl 3 ; (b) fluorinating the compound formed in step (a) to form a compound having the formula CF 3 CXHCXHCF 3 ; (c) converting the compound formed in step (b) by a reaction selected from the group consisting of dehydrohalogenation, dehalogenation and both reactions, to form a compound having the formula CF 3 C = CCF 3 ; and (d) catalytically reducing the compound formed in step (c) with hydrogen to form the compound having the formula (I).
