Catalytic deoxygenation is a fundamental process for bio-oil upgrading due to its high
oxygen content which will result in lower heating value, corrosion and instability issues. The …

An emerging area of the nickel N-heterocyclic carbene (NHC) complexes and their
applications in homogeneous catalysis is highlighted in the review. The review paints a …

Epihalohydrins [2-(halomethyl) oxiranes, 1, 2-epoxy-3-halopropanes](Figure 1) are well-
known versatile synthons and important reagents in the realm of organic synthesis …

ZrOCl2· 8H2O/silica gel as a highly water–tolerant catalyst system has been applied for the
preparation of bis (indolyl) methanes via electrophilic substitution reactions of indoles with …

Lewis acids are important and interesting catalysts in most organic transformations. Among
different Lewis acids, Zr (IV) species such as ZrCl 4 and ZrOCl 2· 8H 2 O are allocated …

Against all odds: Two different cobalt catalyst systems led to the selective isomerization of 1,
3‐dienes. In the case of the [CoBr 2 (py‐imine)]‐catalyzed reaction, the Z‐1, 3‐diene was …

This review provides a comprehensive overview of strategies and methodologies for
reducing C− O and heteroatomic− oxygen bonds (N− O, S− O, P− O) using I2/I−, as well as …

The 1, 4-conjugate addition of indoles and amines to cyclic and acyclic α, β-unsaturated
ketones for C–N bond formation was efficiently carried out under solvent-free conditions at …

ZrCl4 which is commercially available and not a costly compound, is a relatively safe
chemical [LD50 [ZrCl4, oral rat]= 1688mgKg]. In this report we describe the use of ZrCl4 …
