Tetra-tert-butylpyrazole and tetra-tert-butylthiophene

Tetrahedron Letters, 1992
Abstract 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.

Bis(tert-butylsulfonyl)ethyne and 1-tert-butylsulfinyl-2-tert-butylsulfonylethyne

Acta Crystallographica Section C Crystal Structure Communications, 2006
The title compounds are electron-poor ethynes. The structure determination of bis(tert-butylsulfonyl)ethyne, C10H18O4S2, (I), is the first of a bis-sulfonyl-substituted ethyne. The molecule is situated on a crystallographic inversion centre. The S-Csp bond [1.737 (2) A] is the longest of this type reported to date.
