Sonogashira reaction solid support catalysts

Tliere are some excellenl reviews on the use of solid bases in Fine C hemistry 9. 14, 16, 17, 175, 184]. In this section we will comment on some of those base-catalyzed processes. For simplicity purposes, we will not refer to bifunclional catalysis (i.e, metal phase solid base) but only to catalysis by bases. Tlicrefore, for instance, we will not mention on reactions as important as Heck-, Suzuki-, Sonogashira- and Slille-typc ones (248, 249). Similarly, when talking on selective hydrogenation of cilral, wx will not comment on the use of metal-supported catalysts 1250-252], but only on solid bases.
