Castro‐Stephens Coupling
View through CrossRef
Abstract
The preparation of arylacetylenes by the coupling of cuprous acetylides with aryl halides in boiling pyridines is generally known as the Castro–Stephens coupling. Currently, this coupling is one of the most commonly used methods for the synthesis of aryl acetylenes. Moreover, under the Castro‐Stephens coupling condition, acetylenes also couple with vinyl halides or even allyl halides and amines, by which indoles are formed in the coupling with amines.
