The transformation of simple hydrocarbons into more complex and valuable products via catalytic C–H bond functionalisation has revolutionised modern synthetic chemistry. 1111-67-7, Name is Cuprous thiocyanate, belongs to copper-catalyst compound, is a common compound. COA of Formula: CCuNSIn an article, once mentioned the new application about 1111-67-7.
Diazoacetates in coupling reactions: CuI serves as an effective catalyst for coupling terminal alkynes with diazo compounds to generate 3-alkynoates (see scheme). This method is efficient (1:1 ratio of reactants), mild (room temperature), and simple (no additional ligand), and a range of functional groups are tolerated (e.g., C-C double bonds, heteroatoms, and hydroxy groups).
The catalyzed pathway has a lower Ea, but the net change in energy that results from the reaction is not affected by the presence of a catalyst. In my other articles, you can also check out more blogs about 1111-67-7
