H/α-CN and H/β-CN rate ratios have been measured for the solvolysis of sulfonate esters of relatively simple, noncyclic aliphatic alcohols. The β-CN function was found to be far more rate retarding than the α-CN function.

The addition of hydrogen cyanide to both terminal and disubstitutedacetylenes occurs with cis-stereospecificity in moderate to excellent yields when catalysed by a nickel(0) complex.
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
