제목 Acylation of Phenols, Alcohols, Thiols, Amines and Aldehydes using Sulfonic Acid-Functionalized Hyper-crosslinked Poly(2-napthol) as an Efficient Recyclable Catalyst
초록 The cost-effective porous polymers have been fabricated by combining the Friedel–Crafts alkylation of 2-napthol with crosslinking reaction in the presence of formaldehyde dimethyl acetal. The crosslinked poly(2-napthol) reacts with chlorosulfonic acid to obtain sulfonic acid-functionalized polymer with specific surface area of 180 m2/g. The physicochemical properties of the hyper-crosslinked sulfonated polymer is analyzed by fourier transform infrared spectroscopy, X-ray diffraction, thermogravimetric analysis, scanning electron microscopy, Brunauer–Emmett–Teller analysis and X-ray photoelectron spectroscopy. The solid acid shows good catalytic activity for the protection of phenols, alcohols, thiols, and amines with one equivalent amount of acetic anhydride at r.t. In addition, various aldehydes can also be converted to the corresponding gem-diacetates in good yields using one equivalent amount of acetic anhydride.
