On July 31, 2008, Noritake, Shun; Shibata, Norio; Nakamura, Shuichi; Toru, Takeshi; Shiro, Motoo published an article.Application In Synthesis of 2-(2,3-Dihydro-1H-inden-1-ylidene)malononitrile The title of the article was Fluorinated Johnson reagent for transfer-trifluoromethylation to carbon nucleophiles. And the article contained the following:
A novel reagent, [(oxido)phenyl(trifluoromethyl)-λ4-sulfanylidene]dimethylammonium tetrafluoroborate has been developed for the electrophilic trifluoromethylation of carbon nucleophiles. The reagent was designed as a trifluorinated version of a Johnson-type methyl-transfer reagent. The first example of vinylogous trifluoromethylation of dicyanoalkylidenes is also demonstrated. 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
