This literature about this compound(16400-32-1)Quality Control of 1-Bromo-2-pentynehas given us a lot of inspiration, and I hope that the research on this compound(1-Bromo-2-pentyne) can be further advanced. Maybe we can get more compounds in a similar way.

Liang, Yi-En; D. Barve, Balaji; Kuo, Yao-Haur; Fang, Hsu-Wei; Kuo, Ting-Shen; Li, Wen-Tai published an article about the compound: 1-Bromo-2-pentyne( cas:16400-32-1,SMILESS:CCC#CCBr ).Quality Control of 1-Bromo-2-pentyne. Aromatic heterocyclic compounds can be classified according to the number of heteroatoms or the size of the ring. The authors also want to convey more information about this compound (cas:16400-32-1) through the article.

A base-mediated, green, microwave-assisted efficient preparation of a diverse benzoxanthone library from variety of readily accessible γ-alkynyl 1,3-diketones is reported. The synthesis is based on tandem reactions involving intramol. cyclization, propargyl-allenyl isomerization, and electrocyclization in one pot. Some of the benzoxanthones are also synthesized by the one-pot reaction of 1,3-diketone and alkynyl bromide under basic heating conditions. This transformation also results in the construction of one new C-C bond and one new C-O bond.
