A Convenient Synthesis of 2‐Acylphenylacetonitriles
摘要:
The reaction of 2-cyanomethylbenzoyl chloride with Grignard reagents in the presence of cuprous iodide at -5degreesC easily affords 2-acylphenylacetonitriles with good yield.
Two different carbon functional groups can be introduced simultaneously into 1,2-positions of aromatic skeletons based upon a novel insertion reaction of arynes into a carbonyl–cyanomethyl σ-bond of α-cyanocarbonyl compounds.

A synthesis of N-substituted 1-alkyl and 1-aryl 3-aminoisoquinolines by cyclocondensation of 2-
acylphenylacetonitriles with aliphatic and aromatic amines using P2O5/SiO2 as catalysts is described. Selectivity, simplicity
of operation and easy work-up are some advantages of this method.
