2-(Arylylethynylphenyl)-4,4,5,5-tetramethyl-2-imidazoline-1-oxyl 3-oxides 12 and 13 were synthesized by cross-coupling of aryl iodides with 1-alkynes containing the 4,4,5,5-tetramethyl-2-imidazoline-1-oxyl 3-oxide fragment. A procedure was developed for the preparation of 3-and 4-ethynyibenzaldehydes with the use of 2-methylbut-3-yn-2-ol.

Process for the preparation of ethynylbenzaldehydes
-
, (2008/06/13)
A multi-step process for the preparation of ethynylbenzaldehydes from bromo- or iodobenzaldehydes is disclosed. The arylhalogen is replaced with a protected ethynyl compound which is subsequently cleaved by base to form the arylacetylene. The aldehydic functionality is preserved by formation of a corresponding Schiff's base or acetal, and its subsequent regeneration by treatment with aqueous acid.
