Organotin acetylides

Alkynylation of halo acetals. In the presence of ZnCl2 (2 equiv.) the organotin acetylide 1 couples with chloromethyl methyl ether or chloromethyl methyl sulfide to form alkynyl ethers or sulfides, respectively (equation I). [Pg.230]

Similar to alkenyliodonium salts (see Sect. 6.3), aryliodonium salts are highly reactive substrates in Heck-type olefination and other palladium-catalyzed coupling reactions. Aryliodonium salts can serve as very efficient reagents in the palladium-catalyzed arylations of acrylic acid 101 [75], organotin compounds 102 [76], sodium tetraphenylborate 103 [77], and copper acetylide 104 [78] (Scheme 45). [Pg.117]
