nano-bf3.sio2: a reusable and eco-friendly catalyst for thioacetalization and trans-thioacetalization reactions
Authors
abstract
nano-silica supported boron trifluoride (bf3.sio2) is an efficient, reusable and eco-friendly catalyst for chemoselective thioacetalization of aldehydes and ketones. so, this catalyst was applied for transthioacetalization of acetals and acylals into their corresponding 1,3-dithiolanes or 1,3-dithianes in good to excellent yields. the reactions were carried out at room temperature under solvent free and grinding conditions in 1.5-2.5 minutes.
