The solvent-free decarboxylation of carboxylic acids by Pb(OAc)4 affords alkyl radicals, which alkylate 4-methylpyridine, quinoline, and 4-methylquinoline protonated with 2-chlorobenzoic acid. Mechanical activation is required for pyrazine alkylation.

The present invention relates to the field of perfumery. More particularly, it concerns the use as perfuming ingredients of a 2,4-dialkyl-pyridine of formula (I):
in the form of any one of its stereoisomers or a mixture thereof, wherein R
1
represents a C
1-3
alkyl group; R
2
represents a C
4-9
linear alkyl group; and the compound has between 10 and 15 carbon atoms. These compounds are useful for imparting odors of the green and/or pyrazine type. The present invention concerns the use of such compounds in the perfumery industry as well as the compositions or articles containing them.
