Cascade Ring-Opening Dual Halogenation of Cyclopropenones with Saturated Oxygen Heterocycles

Represented is a CuX2- or I2-promoted ring-opening dual halogenation of cyclopropenones with saturated oxygen heterocycles, providing an efficient method for the synthesis of 3-haloacrylates. The ring-opening reaction enables the construction of two C–X (X = Cl, Br, or I) bonds and a C–O bond as well as the cleavage of two C–O bonds and a C–C bond in a single step. This protocol is highly atom economical, has an excellent substrate scope, and exhibits the ability for gram-scale reaction.

Synthesis of 2-methyl-4, 6-diaryl-1, 2, 3-triazinones via diarylcyclopropenones

2-Methyl-4,6-bis(4-substituted-phenyl)-1,2,3-triazin-5(2H)-ones 9a-d were prepared from the coressponding cyclopropenones 4a-d in a similar fashion as described by us previously. One of the the structure of 9b was established by an X-ray analysis.
