Titanium is the second most abundant transition metal and is already a key player in
important industrial processes (eg polyethylene). Titanium is an attractive metal to use for …

The present review deals with the chemistry of the organotitanium species formed by the
reaction of titanium alkoxides of the form XTi (OR) 3 (X¼Me, Cl, OR; R¼alkyl) and excess …

Shortly after the discovery of the proteasome it was proposed that inhibitors could stabilize
proteins which ultimately would trigger apoptosis in tumor cells. The essential questions …

A low-valent titanium generated in situ from Ti (Oi-Pr) 4, Me3SiCl, and Mg powder in THF
reacted with aryl-and alkyl-sulfonamides of aryl and alkyl amines in a reductive N–S/S–O/S …

In this account [3]-and [5] cumulene complexes of group 4 metallocenes that form five-
membered metallacycles are described. These complexes have a “triple bond” despite their …

Niobium complexes in organic reactions have received a lot of attention in recent years.
Niobium is one of the early transition metals, which possess unique reactivity distinct from …

Aliphatic and aromatic sulfonamides were alkynylated with 1-bromo-1-alkynes in the
catalytic presence of CuI to give N-(1-alkynyl) sulfonamides in good to excellent yields. The …

Cyclopropanes are characterized by high ring‐strain energy and have been employed as
useful building blocks in organic synthesis. The incorporation of a heteroatom donor …

Several systems consisting of a ligand, a metal compound, and zinc have been developed
as catalysts for alkyne cycloaddition reactions and alkyne–nitrile co-cycloaddition reactions …
