Abstract 1,7-Diazaperylene and various derivatives were synthesised in an upscaleable route from 1,5-diaminoanthraquinone and its Meerwein reaction with acrylonitrile and subsequent cyclisation with ammonia. The application of tert-butyl alcohol as the solvent led to a significant improvement in the Meerwein reaction. Publication History Received: 30 May 2020 Accepted after revision: 31 August 2020

[Ni(CN)4]2− with NaBH4 or Zn in the presence of excess KCN in water or ethylene glycol, catalyzes hydrocyanation of α,ω-diynes, HC≡C(CH2)nC≡CH to give quantitatively CH3CH(CN)(CH2)nCH(CN)CH3, a newseries of acyclic dinitriles. Importance of the preliminary formation of a (π-acetylene)nickel(0) complex for the hydrocyanation has been suggested.
