The interest in synthesizing heterocycles has always been enormous. The literature contains
a variety of synthetic approaches to the heterocycle ring structures, much of which has been …

In 1836 the first organoselenium compound, diethyl selenide, was prepared by Löwig, 1 and
it was isolated in the pure form in 1869. 2 Early selenium chemistry involved the synthesis of …

Recent progress in the leading synthetic applications of acetylene is discussed from the
prospect of rapid development and novel opportunities. A diversity of reactions involving the …

Tellurium has long appeared as a nearly 'forgotten'element in Biology, with most studies
focusing on tellurite, tellurate and a handful of organic tellurides. During the last decade …

This review presents the recent advances involving several applications of five-membered
cyclic carbonates and derivatives. With more than 150 references, it covers the period from …

In a previous and recent report, 1 we have highlighted in the introductory section the
transition-metal catalysed carbone carbon bond formation as a fundamental reaction in …

The versatility and utility of vinyl chalcogenides in organic synthesis is well documented
through the publication of a number of review articles1 and books. 2 The development of …

This review highlights the hydroelementation reactions of conjugated and separated diynes,
which depending on the process conditions, catalytic system, as well as the type of reagents …

This review summarizes the structural and synthetic aspects of heterocyclic molecules
incorporating an atom of a hypervalent main-group element. The term “hypervalent” has …

We report herein the development of a general and mild protocol of oxygen-promoted Pd (II)
catalysis resulting in the selective cross-couplings of alkenyl-and arylboron compounds with …
