3(5)-(1-Adamantyl)pyrazoles: chemistry and molecular structure
†
Abstract
The synthesis and molecular structure of 3(5)-(1-adamantyl)-4-bromopyrazole (2) are reported. The compound crystallizes in tetramers formed by units of the 5-adamantyl tautomer 2b, linked by N–H⋯
N hydrogen bonds. The results are discussed in the light of other tetramers found in N-unsubstituted
