The Sc(OTf)3-catalyzed C−C bond formation by direct alkylation of quinolines and pyridines using simple alkanes was developed. Various alkanes reacted with quinolines and pyridines to give the corresponding alkylation products in 50−91% yields in the presence of tert-butyl peroxide.

The use of tert-butyl hydroperoxide as an oxidant in Gif-type systems (GoAggIV and GoAgfV) catalyzed by various Fe(III) species is examined. Regioselectivity studids of these systems have revealed several characteristics similar to those observed for other prdviously reported Gif-type reactions. A common rdaction pathway for the GoAggIV and GoAggV oxidation systems and other Gif-type reactions (from

A catalytic amount of benzoylperoxide (BPO)-initiated cross-dehydrogenative coupling reaction of N-iminopyridine ylides with simplealkanes and alcohols leads to the corresponding 2-alkylpyridines with high regioselectivity in moderate to good yields without an additional reduction step to remove the activated group.

The oxidation of cyclooctane using tert-alkyl hydroperoxides under GoAggV conditions has been examined using selected alkyl hydroperoxides as mechanistic probes. The results indicate that the products are formed by alkoxyl radical-induced reactions, there being no need to invoke any chemistry involving high valent iron-oxo species.

GoAggIV chemistry (Fe (III) species, tert-butyl hydroperoxide in a mixture of pyridine and acetic acid) in the presence of LiCl can transform saturated hydrocarbons efficiently into the corresponding alkyl chlorides. The transformation into monosubstituted alkyl derivatives by “ionic trapping” reagents arising from the interception of the first intermediate of the system supports the presence of a
