《Programmed Sequential Additions to Halogenated Mucononitriles》 was written by Zahara, Adam J.; Hinds, Elsa M.; Nguyen, Andrew L.; Wilkerson-Hill, Sidney M.. SDS of cas: 609-08-5 And the article was included in Organic Letters in 2020. The article conveys some information:
Dihalomucononitriles were synthesized and their reactivity evaluated to assess their ability to function as linchpin reagents. Bis(2-chloroacrylonitrile) and bis(2-bromoacrylonitrile) were synthesized from 2,1,3-benzothiadiazole and undergo conjugate addition/elimination reactions with both nitrogen (40-95% yield) and carbon nucleophiles (72-93% yield). Secondary amines undergo monosubstitutions, while carbon nucleophiles are added twice. The sequence of addition of the nucleophiles could be controlled to give mixed addition products. The multicomponent coupling products could then be converted to natural product like motifs using intramol. cyclization reactions. In the experimental materials used by the author, we found Diethyl 2-methylmalonate(cas: 609-08-5SDS of cas: 609-08-5)
Diethyl 2-methylmalonate(cas: 609-08-5) belongs to aliphatic hydrocarbons. Aliphatic hydrocarbons belong to the most abundant fraction in crude oil. Aliphatics molecules are linear or branched open-chain structures such as n-alkanes, isoalkanes, cycloalkanes (naphthenes), terpenes and steranes.SDS of cas: 609-08-5
