One-pot synthesis of various xanthene derivatives using ionic liquid 1,3-disulfonic acid imidazolium hydrogen sulfate as an efficient and reusable catalyst under solvent-free conditions

In this study, 1,3-disulfonic acid imidazolium hydrogen sulfate (DSIMHS) is used as an efficient and reusable ionic liquid for the green, mild, and efficient synthesis of xanthenes under solvent-free conditions. Simple and easy work-up, low cost, green pr

New basic ionic liquid from ethan-1,2-diyl bis (hydrogen sulfate) and DBU (1,8-diazobicyclo[5.4.0]undec-7-ene) as an efficient catalyst for one-pot synthesis of xanthene derivatives

For the first time a new basic ionic liquid from ethan-1,2-diyl-bis (hydrogen sulfate) and 1,8-diazobicyclo[5.4.0]undec-7-ene was suggested. The catalytic activity of the new ionic liquid was tested for synthesis of xanthene derivatives by condensation of aldehydes with i) dimedone ii) β-naphthol iii) 2-hydroxynaphthalene-1,4-dione iv) dimedone and β-naphthol v) 2-hydroxynaphthalene-1,4-dione and dimedone vi) β-naphthol and 2-hydroxynaphthalene-1,4-dione. This approach is a clean, environmentally friendly and convenient work up protocol. The new ionic liquid is an effective and inexpensive catalyst that could easily be recycled and reused five times without significant loss of catalytic activity.
