25 - 074P(RNCH2CH2)3N-Catalyzed α,β-Dimerization of UnsaturatedNitriles: Formation of 2-Alkylidene-3-alkylglutaronitriles. —Base-promoted dimerization reactions of unsaturated nitriles (V) or nitrilesderived in situ from aldehydes/MeCN in the presence of catalyst type (I) lead toformation of glutaronitriles in high yields. No reaction is observed with nitriles(VIII) lacking the γ-hydrogen for activation. — (KISANGA, PHILIP; D’SA,BOSCO; VERKADE, JOHN; J. Org.
