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. ... 

The formation of halogenation products from Grignard reagents and sulfonic acid anhydrides is the result of an oxidative reaction pathway . This side-reaction can be reduced by using sulfonic acid esters, however, in these cases alkylations as well as twofold sulfonylations (cf. corresponding results with sulfonyl fluorides ) are competing (equations 64 and 65).

Table 11.5. Substituted cyclopropanols 31 from carboxylic acid esters and alkenes via ligand-exchanged titanium intermediates generated from Grignard reagents and XTi(OiPr)3 (X = OiPr, Cl, Me).

The procedure described4 is a modification of the method of Khotinsky and Melamed,8 who first reported the preparation of boronic acids from Grignard reagents and borate esters. Benzeneboronic acid and the corresponding anhydride also have been prepared by reaction of phenylmugnesium bromide with boron... 

The best copper reagents are RCu.MgHlg2 and R2Cu.MgHlg derived from Grignard reagents, and R2CuLi (R = primary alkyl). Acetylene is the most reactive alkyne,515 whereas internal acetylenes do not react. 

Symmetrical alcohols can in fact be made in one step from Grignard reagents and esters, as the reaction first produces the aldehyde 57 which is more electrophilic than the ester and so reacts again. There is a warning here Aldehydes cannot be made by acylation of Grignard reagents with esters. But if two reactions are wanted, this is a good method. 

Higher-order cuprates have also been made from Grignard reagents and from organo-zinc species the resulting cuprate reactivity is less for mixed Li/Mg-based systems and mixed Mg/Zn-based ones, although alkylation of primary alkyl iodides may still be accomplished in these cases2,9. 

The free monomeric hydroxy aldehydes are difficult to obtain by hydrolysis of the oximes. Bromomagnesium enolates prepared from Grignard reagents and sterically hindered ketones act as true Grignard reagents. /3-keto alcohols are formed by their reaction with aldehydes or ketones. ...
