Saa, Carlos’s team published research in Synlett in 1994 | CAS: 89245-35-2

2-(4-Bromo-3-indolyl)acetonitrile(cas: 89245-35-2) is a member of nitriles. Nitriles have been reduced to amines by many methods, especially by catalytic hydrogenation and by metal hydrides. Aliphatic and aromatic nitriles have also been reduced to nitro derivatives using hydrazinium monoformate in the presence of Raney-nickel.Computed Properties of C10H7BrN2

Saa, Carlos; Crotts, Dallas D.; Hsu, Gishun; Vollhardt, K. Peter C. published an article in Synlett. The title of the article was 《A cobalt-catalyzed entry into the ergot alkaloids: total syntheses of (±)-lysergene and (±)-LSD》.Computed Properties of C10H7BrN2 The author mentioned the following in the article:

Cocyclization of 4-ethynyl-3-indoleacetonitriles with alkynes in the presence of CpCo(CO)2 gives rise to the ergoline derivatives e.g. I (R = CH2OH, CONEt2), which were transformed into racemic lysergene (II) and LSD, resp. The experimental process involved the reaction of 2-(4-Bromo-3-indolyl)acetonitrile(cas: 89245-35-2Computed Properties of C10H7BrN2)
