Lithium perchlorate suspend in methylene chloride, a mild, efficient and reusable catalyst for the synthesis of ferrocene aminonitrile derivatives

Magnetically separable g‐C3N4 hybrid nanocomposite: Highly efficient and eco‐friendly recyclable catalyst for one‐pot synthesis of α‐aminonitriles

“…Even after 150 years of research, it is apparent that interest in this process is continuing and still this reaction is under active investigation judging from the number of publications . The conventional Strecker reaction employs KCN as the cyanide source with an aldehyde or ketone and a primary amine or ammonia in aqueous solution, which has several drawbacks, such as the high toxicity of KCN, which thus limit the scope of this reaction . Application of trimethylsilylcyanide (TMSCN), which is relatively easy to handle and highly soluble in organic solvents, instead of KCN and HCN as a cyanoanion source provides promising and safer routes to α‐aminonitriles .…”

Superparamagnetic Iron Oxide as an Efficient Catalyst for the One‐Pot, Solvent‐Free Synthesis of 5,5‐Disubstituted Hexahydropyrimidines and Their Spiro Analogues

“…Although this important carbon-carbon bond forming reaction has witnessed much recent progress, [16][17][18][19][20] there are still demands for the development of efficient procedures involving inexpensive, recyclable catalytic systems under solvent-free conditions. including different metal salts [13,14], Fe 3 O 4 was found to be the best catalyst (yield 90%, Table 1, entry 1) for the reaction.…”
