Figure 3
Table of torsion angles, phase angles of pseudorotation (P) and cyclobutane puckering angles in (II) ![[link]](../../../../../../logos/arrows/c_arr.gif) and similar compounds from the Cambridge Structural Database. From left to right, the structural representations illustrate the nomenclature of the torsion angles in the sulfolane ring, with the signs of the torsion angles for the pure envelope conformation; the twist conformation for moleule A of (II); the envelope conformation for molecule B of (II); the chemical structures of similar compounds with data for each compound given in the column below. See Altona & Sundaralingam (1972) and Allen et al. (2005) for definitions and equations. CSD refcodes: DOJPAT = Cadogan et al. (1986); DEKXEW = Cadogan et al. (1985); DIGNOW and DIGNIQ = Williams et al. (1985). |
