1-Phenyl-5-{[2-(trimethyl-sil-yl)eth-yl]sulfon-yl}-1H-tetra-zole.

ABSTRACT: The title compound, C(12)H(18)N(4)O(2)SSi, was synthesized to be employed in a Julia-Kocie?ski olefination. In the mol-ecule, the dihedral angle between the phenyl ring and the tetra-zole ring is 41.50?(5)°. The significantly longer Si-C(methyl-ene) bond [1.8786?(13)?Å] and the shortened adjacent C-C bond [1.5172?(18)?Å], as well as the significant deviation of the corresponding Si-C-C angle [114.16?(9)°] from the ideal tetra-hedral angle, can be attributed to the ?-effect of silicon. In the crystal, mol-ecules are held together by van der Waals inter-actions.

The title compound, C(12)H(18)N(4)O(2)SSi, was synthesized to be employed in a Julia-Kocieński olefination. In the mol-ecule, the dihedral angle between the phenyl ring and the tetra-zole ring is 41.50 (5)°. The significantly longer Si-C(methyl-ene) bond [1.8786 (13) Å] and the shortened adjacent C-C bond [1.5172 (18) Å], as well as the significant deviation of the corresponding Si-C-C angle [114.16 (9)°] from the ideal tetra-hedral angle, can be attributed to the β-effect of silicon.
