Hexafluoroisopropanol dispersed into the nanoporous SBA-15 (HFIP/SBA-15) as a rapid, metal-free, highly reusable and suitable combined catalyst for domino cyclization process in chemoselective preparation of alkyl rhodanines

- 1,1,1,3,3,3-Hexafluoro-2-propanol and SBA-15 mesoporous adduct (HFIP/SBA-15) as simultaneously catalyst.
- Alkyl rhodanine production via domino cyclization is reported.
- A reusable porous catalyst system using commercially available fluorinated alcohol was employed.
- Represents advantages, operational simplicity, no waste, higher yield and with easy workup.
