On January 7, 1999, Konstantinova, Lidia S.; Rakitin, Oleg A.; Souvorova, Ljudmila I.; Rees, Charles W.; White, Andrew J. P.; Williams, David J.; Torroba, Tomas published an article.Recommanded Product: 2-(2,3-Dihydro-1H-inden-1-ylidene)malononitrile The title of the article was One-pot synthesis of new liquid crystalline indeno heterocyclic materials. And the article contained the following:
Disulfur dichloride converts 1-(dicyanomethylene)indane into 2,3-dichloro-1-(dicyanomethylene)indene and dichlorocyanoindeno-1,2-thiazine (I); it also converts inden-3-ylacetic acid into 2,3-dichloro-1-(dichloromethylene)indene and α,2,3-trichloro-1-indenylideneacetylchloride, dichloroindeno[2,1-c]-1,2-dithiolone (II) and dichloroindenothiophenone; upon melting crystals of the 2,3-dichloro-1-(dichloromethylene)indene and dichloroindenothiophenone are strongly birefringent and I exhibits thermochromicity; mechanisms are outlined for the novel transformations and x-ray crystal structures for I and II are analyzed. The experimental process involved the reaction of 2-(2,3-Dihydro-1H-inden-1-ylidene)malononitrile(cas: 2510-01-2).Recommanded Product: 2-(2,3-Dihydro-1H-inden-1-ylidene)malononitrile
