Melamine-derived graphitic carbon nitride as a new effective metal-free catalyst for Knoevenagel condensation of benzaldehyde with ethylcyanoacetate

Abstract

Melamine-derived C3N4 was tested in Knoevenagel condensation of benzaldehyde with ethylcyanoacetate.

NaAlO2‐Promoted Mesoporous Catalysts for Room temperature Knoevenagel Condensation Reaction

“…Condensation reactions are very important in synthetic organic chemistry, which finds potential applications in the syntheses intermediates for anti‐hypertensive drugs, pharmaceutical chemicals and natural products from small molecules . The reaction is usually considered as a probe reaction for evaluating basic strength of the catalysts . The target product, ethyl‐2‐cyano‐3‐phenyl acrylate, detected exclusively with all the catalysts studied for the screenings verified by GC and 1 H‐NMR analysis (Figure S3).…”

Chemoselective heterogeneous iridium catalyzed hydrogenation of cinnamalaniline

“…40-60 µmol/g. 19 The peak temperatures are all in the range of ca. 125-135°C showing that the base sites are of weak strength.…”

One-Step Synthesis of Carbon Nitride Nanosheets for Photoremediation of Toxic Organic Dyes Waste in Aquatic Environment

“…Polimer carbon nitride grafitik berbasis triazin dan poly-heptaazine imide memiliki bentuk dan sifat yang paling mendekati dari g-C3N4 yang ideal [11]. Katalis g-C3N4 juga memungkinkan untuk disintesis baik dari urea yang melalui proses poliadisi langsung menjadi melamin atau langsung dari kondensasi termal melamin [6,12]. Selama proses sintesis g-C3N4, perlu dijaga kondisinya agar tetap zero-oxygen karena sedikit oksigen dapat menghasilkan gas ammonia dan NOx yang beracun [6].…”
