Zur Kenntnis der nickel-katalysierten Mischoligomerisation von Butadien mit Hydrazonen. Vorläufige Mitteilung

Studies on the nickel-catalysed reaction of butadiene with hydrazones The nickel-catalysed reaction of butadiene with methyl-hydrazones yields a series of isomeric azo-compounds identified as 2:1 adducts. The products are compared with those of the analogous reaction of butadiene with imines (cf. Scheme 1–3).
