spectrometry. Detailed optimization of reaction conditions was performed with a wide range of temperatures, in the presence of various types of catalysts and ratios of reagents, to obtain complex information about the process selectivity and develop efficient methods for synthesizing targeted compounds. It was found that precisely optimized approaches provided 3‐buten‐1‐ynes or 1,3‐butadienes with high
