Aminoferrocene, Fe{(η 5 -C 5 H 4 NH 2 )(η 5 -Cp)} is an electron rich amine molecule with a redox-responsive metallocene backbone. Its chemistry has been enriched radically in the past few decades. A number of important uses of aminoferrocene have

FeF3 catalyzed four component reaction under ultrasound irradiation was explored for the first time to prepare N-substituted 2-aminopyridines in good yields. The methodology involved the use of readily available starting materials and PEG-400 under m

Self-assembled copper(II) complexes are described as effective catalysts for nitroaldol (Henry) reactions on water. The protocol involves a heterogeneous process and the catalysts can be recovered and recycled without loss of activity. Further, C2-sy

Copper(II)-catalyzed oxidative cross-coupling of anilines, primary alkyl amines, and sodium azide is described in the presence of TBHP at moderate temperature. This one-pot multicomponent protocol involves a domino C–H functionalization, transimina

We report an efficient procedure for the synthesis of symmetrical disulfanes from organic thiocyanates in the presence of sodium in silica gel at room temperature. By avoiding the use of foul-smelling thiols, the present protocol provides an attracti

Chiral Mn(III)–salalen and –salan complexes derived from (S)-proline have been used as catalysts for the asymmetric Henry (nitro-aldol) reaction. We have also used this methodology for a variety of substrates to afford nitroaldol products in 40

A copper(II)-mediated regioselective N-arylation of azoles has been developed using 8-aminoquinoline amide as a directing group. This reaction shows a broad substrate scope with different azoles such as pyrroles, indoles, pyrazoles and carbazole with

An expedient construction of tetrahydro-β-carbolinediketopiperazine ring systems, which are present in various indole alkaloids, is documented. The synthetic strategy proceeds through a Pictet–Spengler reaction followed by an Ugi-4CR and deprotect

A regiospecific method for the ring-opening reaction of epoxides by the primary, secondary, tertiary alcohols, and aryl, aliphatic amines has been developed using non-toxic metal nitrate salt as a catalyst. The best results were obtained using zircon
