Kemp, W.; Bahl, A. K. published an article in 1971, the title of the article was Nuclear magnetic resonance evidence regarding the stereochemistry of cyanoindanylidene compounds.Application In Synthesis of 2-(2,3-Dihydro-1H-inden-1-ylidene)malononitrile And the article contains the following content:
The stereochemistry of indan derivatives with an exocyclic double bond (I, R = CN, R1 = CO2Et, CO2Me, CN, CONH2, CO2H; R = H, R1 = CN) was deduced from chem. shifts. Stereochem. assignments extend, and are different from, those reported (Jones, G., and Rae, W. J., 1966). 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
