The article presents chemical equation for an article related to Cyclization of 2-Alkynylbromobenzenes with N,N-Dimethyl-2-alkynylanilines by X. Pan and others, published in the periodical "Organic and Biomolecular Chemistry" in 2014.

The article presents chemical equations for the article "Assembly of Indeno[1,2-c]chromenes via a Palladium-Catalyzed Reaction of 1-Bromo-2-(cyclopropylidenemethyl)benzene with 2-Alkynylphenol" by X. Pan and others, published in the periodical "Advanced Synthesis & Catalysis" in 2014.

An abstract of the article "Route to Pyrazolo[5,1-a]isoquinolines via a Copper-Catalyzed Tandem Reaction of 2-Alkynylbromobenzene with Pyrazole," by Xiaolin Pan, Yong Luo, and Jie Wu is presented.

An efficient tandem one-pot procedure with the formation of three C-C bonds for the synthesis of the title compounds is developed from easily available starting materials. [ABSTRACT FROM AUTHOR]

The tandem reaction involves a double insertion of triple bonds and is not sensitive to the nature of substituents on both reagents. [ABSTRACT FROM AUTHOR]
