Kerr constants and spatial structures of certain aryl vinyl compounds of sulfur

Abstract

1. The aryl group is rotated by an angle of 65-75° with respect to the C-S-C plane in the aryl vinyl sulfones and their β-chloroderivatives containing H, CH3, CL, and Br substituents; in nitrophenyl vinyl sulfone, the rotation is 4-28°. 2. The unsaturated group inthe aryl vinyl sulfones, aryl trans-β-chlorovinyl sulfones, and the aryl trans-β-chlorovinyl sulfides have s-trans conformation, or something close thereto, displacement out of the C-S-C plane being as high as 40°. © 1977 Plenum Publishing CorporationPlenum Publishing Corporation.
