Disclosed herein is a process comprising contacting a haloalkane reactant with an olefin in the presence of a catalyst system that consists of metallic iron and a phosphine to produce a haloalkane insertion product, wherein said haloalkane reactant is an alkane substituted with at least one halogen selected from the group consisting of F, Cl, and combinations thereof. Also disclosed herein is a process comprising contacting CF3CCl3 with CH2=CHX in the presence of a catalyst system that consists of metallic iron and a phosphine to make CF3CCl2CH2CHClX, wherein X = F or Cl. Also disclosed are further reactions in a sequence to produce HFO-1336ze and HCFO-1335zd. Also disclosed herein is a new composition comprising the compound CF3CF2CH=CHCl.
