The diseision by TMPO- of up to 93% of the reaction of cycloheptyl bromide suggests that K is the dominant, probably exclusive, pathway for Grignard reactions of typical alkyl halides I3. The dominance of pathway R is also supported by the agreenrent between observed yields and quantitative D-modcl predictions [83]. 

Asoln.of cycloheptyl bromide in tetrahydrofuran injected at 25° into a vigorously stirred soln. of lithium hydridotriethylborate in the same solvent, and stirring continued 3 hrs. cycloheptane. Y 99%. - Lithium hydridotriethylborate is a nucleophilic reducing agent far superior to LiAlH4. Compared to LiBH4, its nucleophilicity is enhanced by a factor of 10,000. F. e. s. H. C. Brown and S. Krishnamurthy, Am. Soc. 95, 1669 (1973) replacement with NaAlH iOCH.,-in the presence of palladium chloride complexes cf. I. Simunek and M. Kraus, Coll. 38, 1786 (1973).

Using cyclopentylmagnesium bromide, cyclohexylmagnesium bromide, cycloheptyl-magnesium bromide, benzylmagnesium bromide, or 2-phenylethylmagnesium bromide rather than isopropylmagnesium bromide in this sequence led to a variety of... 

Li and coworkers reported the conjugate addition of alkyl groups to enamides mediated by zinc in aq. NH4CI to generate a -amino acid derivatives (Eq. 4.73). No reaction was observed in the absence of water. Both secondary and tertiary alkyl groups such as linear (2-butyl, 2-propyl, 2-pentyl), cyclic (cyclohexyl, cyclopentyl, cycloheptyl), and bulky ones (tert-butyl) were all transferred to the substrate successfully. Even simple primary iodides and methyl iodide provided the desired products in good yields. Miyabe et al. as well as Jang and Cho reported the addition of alkyl radicals from alkyl iodide to a,p unsaturated ketones, esters, and nitriles mediated by indium in aqueous media. Indium-mediated Michael addition of allyl bromide to l,l-dicyano-2-arylethenes also proceeded well in aqueous medium. ...
