One-stage synthesis has been developed for the preparation of adamantyl-containing difluoroboron complexes of 1,3-dicarbonyl compounds from 1-(1-adamantyl)ethanone, boron trifluoride etherate, and carboxylic acids anhydrides. The reaction of the complexes with hydrazine hydrate and its derivatives afforded the corresponding adamantyl-containing pyrazoles.
