Abstract
All eight possible bicyclic molecules beta-P4SnSe3-n(I)CHI2 (n = 0-3) were formed on reaction of mixtures of the tricyclic compounds P4SnSe3 -n with CHI3 in solution in CS2, and identified in the reaction mixtur e by analysis of their P-31 NMR spectra. Differences in coupling const ants caused by the presence of sulfur rather than selenium in the prod ucts were interpreted in terms of concerted twisting of the fused five -membered rings, caused by a combination of the unsymmetric exocyclic ligand and endocyclic chalcogen substitution.
