Synthesis of 1,1-dibromoalkenes


Recent Literature

Activation of the C-Br bond of CBrX3 (X = Cl, Br) using 9-mesityl-10-methylacridinium perchlorate as a visible-light photocatalyst enables the synthesis of gem-dihaloenones from terminal alkynes via a SET mechanism.

A base-promoted dibromination of enamides using CBr4 as a bromine source provides β,β-dibrominated secondary enamides. These novel products can be readily transformed to 5-Br oxazoles via Cu(I) catalyzed intramolecular cyclization in good yields.
