Benzylic C-H arylation of azaarylmethanes with aryl sulfides has been developed by using a Pd-NHC catalyst and an amide base. Various azaarylmethanes and aryl sulfides were involved in the reaction to afford the corresponding diarylmethanes in good to excellent yields. Moreover, triarylmethane synthesis was accomplished through iterative arylations of 2- or 4-methylpyridine with two different aryl sulfides.
Regioselective synthesis of 4-alkylpyridines from pyridine and aldehydes via dipole reversal process of 1,4-dihydropyridine phosphonate

4-Alkylation of pyridine has been accomplished by the reaction of ylides, derivated from 1,4-dihydropyridine phosphonate via phosphonioalkoxycarbonylation of pyridine with aldehydes and subsequent elimination of diisopropyl phosphate followed by aromatization with potassium tert-butoxide.
A facile synthesis of functionalized 4-benzylpyridines by using mixed copper, zinc benzylic organometallics
Chia,Shiao
, p. 2033 - 2034 (2007/10/02)
A general approach by use of highly functionalized mixed copper zinc, benzylic organometallics to react with N-ethoxycarbonylpyridinium chloride to give regioselectively 4-benzylpyridines after oxygen oxidation in 30-75% yield is described.
