Tetra-tert-butylpyrazole and tetra-tert-butylthiophene

Tetra-tert.butylpyrazole (4) and tetra-tert.butylthiophene (11) were prepared starting from the seven membered cycloalkyne 1 and a reductive desulfurization in the last step. Some reactions of 4 and 11 are described. X-ray structural analyses of 11 and the corresponding S,S-dioxide were carried out.
