Provided is an efficient HCFO-1437dycc production method for producing HCFO-1437dycc with a high yield at a high selective rate through an industrially advantageous process by using easily available raw materials. This production method for 1-chloro-2,3,3,4,4,5,5-heptafluoropentene is characterized by causing 5-chloro-1,1,2,2,3,3,4,4-octafluoropentane (HCFC-448occc) to undergo defluorination and hydrogenation in an aqueous solution of a base to obtain 1-chloro-2,3,3,4,4,5,5-heptafluoropentene (HCFO-1437dycc). |
