In the present review, we discuss recent progress in the field of C–Z bond formation
reactions (Z= S, Se, Te) catalyzed by transition metals. Two complementary methodologies …

The development of synthetic methods for the introduction of the fluorine atom and
fluoroalklyl groups into organic molecules has gained increased attention. Synthetic organic …

Fluorine, often called as “a small atom with a big ego”, 1 lies in the second row and the 17th
column in the periodic table of the chemical elements. This unique position in the periodic …

1. INTRODUCTION Fluorine is the most abundant halogen in the Earth, s crust. 1 However,
only a dozen fluorinated organic compounds have been identified in nature. 2 Most of the …

Cu-catalysed arylation reactions devoted to the formation of C–C and C–heteroatom bonds
(Ullmann-type couplings) have acquired great importance in the last decade. This review …
