Can acyclic conformational control be achieved via a sulfur-fluorine gauche effect? [PDF]

, 2015
The gauche conformation of the 1,2-difluoroethane motif is known to involve stabilising hyperconjugative interactions between donor (bonding, σC-H) and acceptor (antibonding, σ*C-F) orbitals.

Benzhydryl phenyl sulfone [PDF]

Acta Crystallographica Section E Structure Reports Online, 2009
In the title compound, C(19)H(16)O(2)S, the sulfur-bound phenyl group is approximately parallel to one of the two phenyl rings of the benzhydryl group, making a dihedral angle of 12.53 (10)°, and forms a dihedral angle of 41.25 (9)° with the other phenyl ring. In the crystal, weak C-H⋯O inter-actions form a two-dimensional network propagating along the
