secondary benzylic halidesDMFHMPAALDEHYDESKETONESMECHANISMReductive coupling of secondary benzylic halides is reported with sodium dithionite in dry DMF or HMPA at 155-160degreesC under N-2 atmosphere. Primary benzylic and allylic halides gave the reductively coupled dimers and/or sulfones. The ...

Synthesis of branched or linear prenylated benzylic imines. Recently, O’Broin and Guiry63 established the palladium-catalyzed synthesis of 2-amino-1,3-dienes 93 from the propargylic precursors 92 (Scheme 42). The mild reaction conditions showed broad functional group tolerance. Various amine ...
In this context, electrophilic LTM activation of carbon–carbon unsaturations, adjacent to alcoholic moieties (i.e., allylic, benzylic, and propargylic alcohols, usually referred to as π-activated alcohols), deserves a particular mention [10–13]. As a part of our ongoing interest in the gold...

2007, Pages 2439-244 reports that various allylic and benzylic substrates were selectively oxidized to the corresponding enones in good yields using sodium chlorite, either in combination with tert-butyl hydroperoxide in stoichiometric conditions, or associated with N-hydroxyphthalimide as catalyst. These ...
