Usage

Uses

Different sources of media describe the Uses of 75732-01-3 differently. You can refer to the following data:
1. Starting material for a variety of copper(I) complexes.
2. Mesitylcopper(I) is can be used to synthesize: Homo and heteroleptic copper(I) complexes such as Cu(I) alkoxides, siloxides, phosphates, amides, and phosphides.Biorelevant copper(I) complexes as biomimetic model compounds. Copper nanoparticles from stabilizing primary amines. It can also be used as a selective mesityl group transfer reagent in stoichiometric C?C and C?heteroatom bond-forming reactions.
3. Mesitylcopper is an organometal used to synthesize compounds such as copper diketonate complexes.

General Description

Mesitylcopper(I) is a thermally stable and highly soluble organocopper compound, which is commonly used as a metalation reagent in organic synthesis. In mixed lithium cuprate reagents, mesitylcopper serves as a useful ″holding group″. It is very sensitive to moisture and air therefore reactions must be carried out under anhydrous conditions.

Synthesis and Reactivity of Fluoroalkyl Copper Complexes by the Oxycupration of Tetrafluoroethylene

The copper(I)-mediated generation of -OCF2CF2- moieties by the oxycupration of tetrafluoroethylene (TFE) using either copper aryloxides or alkoxides is disclosed. The key intermediates, 2-aryloxy-1,1,2,2-tetrafluoroethyl and 2-alkoxy

Enantioselective Borylative Dearomatization of Indoles through Copper(I) Catalysis

The enantioselective borylative dearomatization of a heteroaromatic compound has been achieved using a copper(I) catalyst and a diboron reagent. This reaction involves the regio- and enantioselective addition of active borylcopper(I) species to indole-2-carboxylates, followed by the diastereoselective protonation of the resulting copper(I) enolate to give the corresponding chiral indolines, which bear consecutive stereogenic centers.

Isolation and X-ray crystal structures of triarylphosphine radical cations

Salts containing triarylphosphine radical cations 1?+ and 2?+ have been isolated and characterized by electron paramagnetic resonance (EPR) and UV-vis absorption spectroscopy as well as single-crystal X-ray diffraction. Radical 1?+ exhibits a relaxed pyramidal geometry, while radical 2?+ becomes fully planar. EPR studies and theoretical calculations showed that the introduction of bulky aryl groups leads to enhanced p character of the singly occupied molecular orbital, and the radicals become less pyramidalized or fully flattened.
