Organometallic compounds palladium-catalyzed coupling

Palladium-catalyzed coupling reactions of 2-(5-iodoisoxazol-3-yl)pyridine 274 with a variety of organometallic compounds led to derivatives 275-278 through Sonogashira, Suzuki, Negishi, and Stille reactions, respectively (Scheme 64) <20010L4185>. [Pg.411]

Palladium-catalyzed coupling reactions of organozinc compounds with acyl halides are the fastest and mildest among the known methods using a variety of organometallic compounds. [Pg.646]

Transition metal-catalyzed cross-coupling reactions between vinyl organometallic compounds and unactivated alkyl halides that can be usually performed with palladium, nickel and cobalt are of particular synthetic interest [37-39]. Recently, the groups of Cahiez [48] and Cossy [49] concurrently reported the first iron-catalyzed reaction of alkenyl Grignard compounds with primary and secondary alkyl halides (X=Br, I) (Scheme 5.15). The two protocols basically differ in the iron source... [Pg.164]

In some cases, it is possible to couple an alcohol with an organometallic compound. Allylic alcohols are coupled with alkylmagnesium bromides in the presence of Ti(OiPr)4, for example. Allylic alcohols can be coupled with arylboronic acids in ionic liquid solvent and a rhodium catalyst. The palladium-catalyzed... [Pg.614]
