Reagents aryl iodide

Without additional reagents Aryl iodides from aryl hydrazines s. 13, 580... [Pg.537]

Indol-2-ylcopper reagents can also be prepared from 2-lithioindoles and they have some potential for the preparation of 2-substituted indoles. 1-Methyl-indol-2-ylcopper can be prepared by reaction of 2-lithio-l-methylindole with CuBr[10]. It reacts with aryl iodides to give 2-aryl-1-methylindoles. Mixed cyanocuprate reagents can be prepared using CuCN[ll], The cyan-ocuprate from 1-methylindole reacts with allyl bromide to give 2-allyl-l-methylindole. [Pg.97]

Organolithium reagents (Section 14 3) Lithi um metal reacts with organic halides to pro duce organolithium compounds The organic halide may be alkyl alkenyl or aryl Iodides react most and fluorides least readily bro mides are used most often Suitable solvents include hexane diethyl ether and tetrahy drofuran... [Pg.615]

Formation of aryl Grignard reagents (Section 14 4) Aryl halides react with magnesium to form the corresponding arylmagnesium halide Aryl iodides are the most reac tive aryl fluorides the least A similar reaction occurs with lithium to give aryllithium reagents (Section 14 3)... [Pg.974]

BURTON Trilluoromelhylation Tnfluoromethylation of aryl iodides with Cd (Cu) reagents... [Pg.57]

The perfluoroacetylenic copper compounds undergo coupling reactions with aryl iodides and provide a useful synthetic route to the perfluoroalkyl aryl alkynes [147, 255] (equation 170) Coupling of these copper reagents with the 1-iodo-perfluoroalkynes gives the perfluorodiynes [747 255] (equation 171)... [Pg.711]

The order of reactivity of halides with magnesium is RI > RBr > RC1 (very few organomagnesium fluorides have been prepared), i) Aryl Grignard reagents are more easily prepared from aryl bromides and aryl iodides than from aryl chlorides, which react very sluggishly. [Pg.479]

This is a very rare metal in cross-coupling reactions. Direct comparison of similar methylating reagents derived from Al, Ga, and In showed that the Ga derivative is the least reactive.165 Vinylgallium dichlorides underwent cross-coupling with aryl iodides in the presence of Pd catalysts with P(o-tol)3 the reaction is moderately tolerant to acidic functional groups.166... [Pg.320]
