The reaction between trihaloisocyanuric acids and alkynes in the presence of acetic acid provides an efficient methodology for preparation of β-haloenol acetates in yields ranging from 34 to 94%, depending on the halogen and alkynes used. This methodology provides an alternative to typical procedures, which usually employ metal catalysis and are limited to terminal alkynes.

An efficient and simple N-bromosuccinimide-mediated two-step synthesis of substituted quinoxalines from 1,2-diarylacetylenes and 1,2-diaminobenzenes in boiling AcOH, during a one-pot procedure has been developed. All the structures of the substituted quinoxalines were confirmed, some by single-crystal X-ray crystallography. Possible reaction pathways were discussed, and some data were matched with the previous work.
