Cumulenes are organic molecules with two or more cumulative (consecutive) double bonds. Their reactions often proceed at room temperature, with or without a catalyst, and are stereospecific, giving the reaction products in high yields – features characteristic of “click reactions”. Cumulenes in Click Reactions presents a comprehensive list of cumulene systems and their reactions, with an emphasis on their “click-like” nature. The chapters are structured according to the number of carbon atoms in...
