On January 31, 2006, Zahouily, Mohamed; Bahlaouan, Bouchaib; Abrouki, Younes; Salah, Mohamed; Bahlaouan, Ouafa; Rayadh, Ahmed; Aadil, Mina; Sebti, Said published an article.Application In Synthesis of 2-(2,3-Dihydro-1H-inden-1-ylidene)malononitrile The title of the article was Natural phosphate and potassium fluoride doped natural phosphate as new catalysts for the Vilsmeier-Haack type reaction. And the article contained the following:
The catalytic activity of the inexpensive natural- or potassium fluoride doped- phosphates as bases was evaluated in a Vilsmeier-Haack type reaction. High efficiency, in term of chem. yields and reaction rates was found in the preparation of 2-chlor-3-cyanopyridines starting from 2-propylidene-malononitriles. The experimental process involved the reaction of 2-(2,3-Dihydro-1H-inden-1-ylidene)malononitrile(cas: 2510-01-2).Application In Synthesis of 2-(2,3-Dihydro-1H-inden-1-ylidene)malononitrile
