Synthesis of perimidines in the presence of Fe3O4@nano-cellulose/BF3 as a super paramagnetic nanocatalyst

Nanocelluloseas as light weigh, nontoxic, accessible and low price material [1] is generally produced from partial hydrolysis of cotton. Magnetic nanocelluloseis prepared from reaction of nanocellulose with FeCl3 and FeCl2 in a simple reported procedure. Fe3O4@nano-cellulose/BF3 as a new super paramagnetic nano catalyst is prepared from supporting of BF3 on magnetic nano cellulose. The structure of nano catalyst was suggested by FT-IR, VSM, XRD, XRF, EX, FESEM, TEM and TGA techniques. This nano catalyst is removed from reaction medium by an external magnet. Perimidines constitute an important class of natural and non-natural products. They have attracted great attention in synthetic organic chemistry for several reasons, including biological activities, pharmacological applications such as analgesic, antitumour, antiviral, antipyretic, antiparkinsonian, antirheumatic, antifungal, and optoelectronic properties [2, 3] . In this investigation, perimidines were synthesized in excellent yield by condensationof aldehydes and 1,8-diaminonaphthalenein the presence of Fe3O4@nanocellulose/ BF3. The FT-IR, 1HNMR and 13CNMR spectra confirmed the structure of compounds.This approach offers many advantages such as good yields, short reaction time, easy workup, inexpensive and efficient catalyst
