Abstract
Metallopropargylation of a number of carbazoles was performed by dicobalt hexacarbonyl complexes with propargyl alcohol and 1,4-butynediol in the presence of boron trifluoride etherate. It was shown that depending on the substituents position in the carbazole ring occurred either N- of C-propargylation; with 1,4-butynediol formed also oligomeric products.
