Direct chlorination of 2-(2H-hexafluoropropyl)-tetra- hydrofuran 1 gave high yield of 2-(2-chlorohexafluoropropyl)- pentachloro-2,5-dihydrofuran 2. Bromination of 1 gave very complex mixture of products, from which three compounds, viz. 2-bromo-5-(2H-hexafluoropropyl)-furan 3, 3-bromo-5-(2H-hexafluoropropyl)-furan 4, and 2,4-dibromo-5-(2H-hexafluoropropyl)furan 5 were isolated.
