With their mechanistic novelty and various modalities of reactivity, transition metal
unsaturated carbene (alkenylidene) complexes have emerged as versatile intermediates for …

The propargylation reaction is one of the most important fundamental reactions in organic
synthesis. It features mild reaction conditions, a tolerance of a diverse range of functional …

The direct functionalization of aromatic compounds, via Friedel–Crafts alkylation reactions
with alcohols, is one of the cornerstones in organic chemistry. The present emerging area …

In sharp contrast to the well‐established transition metal‐catalyzed allylic substitution
reactions, the study of the corresponding propargylic substitution reactions has been quite …

Abstract In 2005, the ACS Green Chemistry Institute (GCI) and the global pharmaceutical
corporations developed the ACS GCI Pharmaceutical Roundtable to encourage the …

Recent advances in the transition-metal-catalyzed enantioselective propargylic substitution
reactions of propargylic alcohol derivatives with nucleophiles are reviewed in this article …

Bimolecular nucleophilic substitution reactions of alcohols are fundamentally important
transformations in organic chemistry yet, to date, they are relatively underdeveloped with …

Although the free allenylidene species: CdCdCH2 was originally identified in 1961 (trapped
in cold matrixes), 1 it is 1976 when the isolation of the first allenylidene complexes [M …

The FeCl3-catalyzed C3-selective Friedel–Crafts alkylation of indoles using allylic, benzylic
and propargylic alcohols has been developed. The reaction was performed in the presence …

We investigate a group B• that includes Artin's braid group B∞ and Thompson's group F.
The elements of B• are represented by braids diagrams in which the distances between the …
