Copper-catalyzed distannylation of alkynes.
نویسندگان
چکیده
A copper(I)-phosphine complex has been found to facilely promote the distannylation of alkynes with the aid of a base, where a catalytically generated Cu-Sn species serves as a key intermediate. The broad versatility of the copper catalysis has been demonstrated by the facile distannylation of unfunctionalized aliphatic alkynes, being hardly achievable with the conventional palladium catalysts.

Copper-catalyzed addition of H-phosphine oxides to alkynes forming alkenylphosphine oxides.
We have developed efficient copper-catalyzed additions of P(O)H compounds to alkynes, and the reactions provided the regio- and stereoselective E-alkenylphosphine oxides under catalysis of the commercially available and inexpensive copper catalyst system CuI/ethylenediamine. This finding is the first example of copper-catalyzed hydrophosphinylation of alkynes to synthesize alkenylphosphine oxides.
متن کاملArylmagnesiation of alkynes catalyzed cooperatively by iron and copper complexes.
Iron and copper complexes cooperatively catalyzed the arylmagnesiation of unfunctionalized alkynes including dialkylacetylenes, where the presence of both iron and copper catalysts is essential for high yields of 2-aryl-1-alkenylmagnesium bromides.

متن کاملCopper Catalysis for Synthesizing Main‐Group Organometallics Containing B, Sn or Si
A copper complex has proven to be a potent catalyst for forming a C-B bond via diborylation of arynes and alkynes, affording vic-diborylarenes and vic-diborylalkenes with high efficiency. A boryl-substituted organocopper species, which is intermediately generated in the diborylation, has been found to be captured by a tin or a carbon electrophile, leading to three-component borylstannylation or...

In this work, copper(II) heterogeneous nanocatalyst supported on modified AlPO4 (Cu(II)-DA@Nano AlPO4) was used for the synthesis of some biological active heterocyclic molecules, particularly for the efficient conversion of a wide range of non-activated terminal alkynes to β-hydroxy 1,4-disubstituted 1,2,3-triazolethrough a three-component “click” reaction at room temperature in water. The reg...
