Gram-Scale Synthesis of Cu(II)@COF via Solid-State Coordination Approach for Catalysis of Alkyne-Dihalomethane-Amine Coupling
A novel covalent organic framework material COF-DM, which contains chelating coordination environments, was synthesized at the gram level under mild conditions. In addition, its Cu(II)-loaded complex of Cu(II)@COF-DM was prepared by impregnating COF-DM in
Recyclable Cu/C3N4 composite catalyzed AHA/A3 coupling reactions for the synthesis of propargylamines
The heterogeneous Cu/C3N4 catalyst was found to be efficient for the synthesis of propargylamines using a three-component coupling reaction of alkynes, CH2Cl2 and amines (AHA) without additional base. Moreover,
Silica nanospheres supported diazafluorene iron complex: An efficient and versatile nanocatalyst for the synthesis of propargylamines from terminal alkynes, dihalomethane and amines
We present the synthesis of an efficient heterogeneous silica nanosphere supported iron catalyst (SiO2@APTES@DAFO-Fe) and its catalytic application in a one pot three-component coupling reaction of terminal alkynes, dihalomethane and secondary

Nickel-catalyzed three-component coupling reaction of terminal alkynes, dihalomethane and amines to propargylamines
Direct C - H and C - halogen activation is an important and practical task in C - C, C - N bond formation reactions using alkynes. Propargylic amines are synthetically versatile intermediates for the preparation of many nitrogen-containing biologically ac

Cobalt-catalyzed alkyne-dihalomethane-amine coupling: An efficient route for propargylamines
A cobalt-catalyzed three-component coupling of terminal alkynes, dihalomethanes, and amines was developed. This method offers an efficient way for propargylamines via the dual activation of C-H and C-halogen bond. The reaction uses cheap CoBr2

Copper-catalyzed three-component coupling of terminal alkyne, dihalomethane and amine to propargylic amines
The direct C-H and C-halogen activation for C-C bond formation is one of the most interesting reactions in organic chemistry. C-C bond formation using alkynes as a carbon nucleophilic source is a very useful method in synthesis. Herein, a copper(I) chlori
