eurjchem-211	Khalil, Khaled; Al-Matar, Hamad; Elnagdi, Mohamed	Chitosan as an eco-friendly heterogeneous catalyst for Michael type addition reactions. A simple and efficient route to pyridones and phthalazines	2010	7	.pdf	application/pdf	3762	254	75	Reaction  of  pyridazinones  with  a  mixture  containing  benzaldehyde,  malononitrile  and  chitosan  affords  phthalazines  that  are  also  produced  by  reaction  of  pyridazinone with benzylidene‐malononitrile.  Being  hydrophilic  and  possessing  basic  moieties, [1‐3] chitosanhas been utilized as heterogeneous eco‐ friendly basic catalyst for reactions carried out in protic media  [4]. 	cache/eurjchem-211.pdf	txt/eurjchem-211.txt
