A novel and regioselective Ni(I) catalyzed C–C and C–N cascade couplingreactions has been developed. The cascade furnishes atom-economic access to 40 3-aryl-1-aminoisoquinolines. The regioselectivity of C(sp3)-cyano group over C(sp2)-cyano group was revealed and supported by mechanism studies as well as the preliminary density functional theory (DFT) calculations.
Meltedpoly(ethyleneglycols) (PEGs) were used for the first time as solvent for the sonochemically promotedcyanation of arylhalides employing inexpensive and safe K4[Fe(CN)6] and a relatively low amount of Cu‐based catalyst. The Mw (weight‐average polymer molecular weight) of PEG proved to notably influence the substrate conversion, which is indicative of a strong dependence of the sonication efficacy
