Grignard reagents, and halides

Benzvlic Grignard reagents and halides have been discussed previously (Sections 2.4.1.1 and 2.4.21. For eilher. low yields and homo-coupling are frequently (hut not always) encountered, and an SHT mechanism (or possibly unintentionally catalyzed side reactions) may be involved. [Pg.46]

Alkyl and arylboranes are obtained (35) from BF using the appropriate Grignard reagent, alkylalurninum halide, or zinc alkyl, using diethyl ether as the solvent (see also Organometallics) ... [Pg.160]

Perfluorovinyl organotin compounds can be prepared from perfluorovinyl Grignard reagents and organotin halides [76] (equation 11) Yields are slightly improved under Barbier conditions [76]... [Pg.672]

The 1-alkyl-diaziridines can easily be hydrolyzed to alkyl hydrazines. Hence alkyl hydrazines are easily available from Grignard reagents and thus from alkyl halides. The three last examples of Table XII show the yield of alkyl hydrazine calculated on the diazirine used. The reaction has preparative interest because the alkylation of hydrazine with alkyl halides only gives monoalkyl hydrazines in exceptional cases. ... [Pg.128]

A variety of organometallic compoundshave been used to couple with alkyl halides. " Organosodium and organopotassium compounds are more reactive than Grignard reagents and couple even with less reactive halides. Organolithium... [Pg.536]

Grignard reagents and organolithium compounds abstract protons that are much less acidic than those of water and alcohols => a useful way to prepare alkynylmagnesium halides and alkynyllithium. [Pg.481]
