A highlyefficient one‐pot procedure for the preparation of 1‐chloroalkynes and 1‐chlorobutadiynes from terminal and trialkylsilyl‐protected precursors is reported. This convenient reaction, proceeding under mild conditions, utilizes N‐chlorosuccinimide as the chlorinating agent and tolerates a range of functional groups.

We report an additive-free, base-catalyzed C–, N–, O–, and S–Si bond cleavage of various organosilanes in mild conditions. The novel catalyst system exhibits high efficiency and good functional group compatibility, providing the corresponding products in good to excellent yields with low catalyst loadings. Overall, this transition-metal-free process may offer a convenient and general alternative to
