Synthesis of 3-(1-Adamantyl)pyrazole and 3,5-Di(1-adamantyl)pyrazole in a Microwave Oven

Abstract
An extraordinary inversion of the regioselectivity in the reaction of C-adamantylation of pyrazoles by 1-bromoadamantane was observed when the autoclave vessel was replaced by a microwave oven. In these last conditions mono and disubstituted 3(5)-(1-adamantyl) pyrazoles were obtained.
