Hindered t-alkyl halides with lithium triethylborohydride in the presence of chromous chloride furnish highly crowded coupled products in good yield (equation 111) . Alkanes obtained by hydroalumination of alkenes with LAH in the presence of titanium tetrachloride can be dimerized in the presence of cupric acetate to furnish alkanes (equation 112) ... [Pg.587]

Lithium triethylborohydride continues to be a useful synthetic reagent. It has been reported that this reagent in THF reduces the toluene-p-sulphonates of primary and secondary alcohols to the corresponding alkanes. The reduction is even applicable to tosylates of cycloalkanols, hindered alcohols, and polyhydroxy derivatives. The reaction of lithium triethylborohydride with elemental sulphur has been reported to form rapidly Li aS or Li aS a (depending upon the stoicheiometry), which can then be used to prepare sulphides, RaS, and disulphides, RaS a, in high yield. Similarly, the publication of a convenient... [Pg.40]

Lithium triethylborohydride has been shown to be an excellent reagent for the rapid reduction of alcohol tosylates to alkanes, even in hindrred cases. A comparative study on cyclohexyl tosylate marked out this reagent or the 9-BBN derivative (45) as the reagents of choice, but LiEtsBH is more readily available. [Pg.146]
