چکیده

Efficient and recyclable novel nano tetra‐2,3‐pyridiniumporphyrazinato‐oxo‐
vanadium tricyanomethanide, {[VO(TPPA)][C(CN)3]4}, as a vanadium surface‐free
phthalocyanine‐based molten salt catalyst was successfully designed, produced and
used for the Strecker synthesis of α‐aminonitrile derivatives through a one‐pot
three‐component reaction between aromatic aldehydes, trimethylsilyl cyanide and
aniline derivatives under neat conditions at 50 °C. This catalyst was well characterized using Fourier transform infrared, UV–visible, X‐ray photoelectron and energy‐
dispersive X‐ray spectroscopies, X‐ray diffraction, scanning and high‐resolution
transmission electron microscopies, inductively coupled plasma mass spectrometry
and thermogravimetric analysis. The catalyst can be simply recovered and reused
several times without significant loss of catalytic activity.
