The endocyclic restriction test: The geometries of nucleophilic substitutions at sulfur(VI) and sulfur(II)

(Chemical Equation Presented) The trajectories for nucleophilic substitutions at sulfur(VI) and sulfur(II) have been investigated by the endocyclic restriction test. On the basis of double-labeling experiments, the sulfur(VI) transfer in the conversion of 1 to 2 is found to be intramolecular, while the sulfur(VI) transfer in the conversion of 3 to 4 and the sulfur(II) transfer in the conversion of 5 to 6 are found to be intermolecular. These results are taken to be consistent with transition structures for these sulfur transfer reactions which require a large angle between the entering and leaving group, a geometry analogous to apical group positions in trigonal bipyramidal transition states.

Generation, Isolation, and Characterization of N-(Arylthio)-7-tert-butyl- and N-(Arylthio)-2,7-di-tert-butyl-1-pyrenylaminyl Radicals

N-(Arylthio)-7-tert-butyl-1-pyrenylaminyl (2) and N--2,7-di-tert-butyl-1-pyrenylaminyl radicals (3) are prepared by PbO2 oxidation of N-(arylthio)-7-tert-butyl-1-aminopyrenes and N--2,7-di-tert-butyl-1-aminopyrene, respectively, and studied by ESR and ENDOR spectroscopy.The kinetic ESR study shows that, while aminyls 2 gradually decompose in solution at room temperature, aminyl 3 is quite persistent, even in refluxing benzene, and shows no tendency to dimerize, even at low temperatures.These interesting properties of 3 permit us to isolate 3 as radical crystals in 28-31percent yield.The hyperfine splitting (hfs) constants of 2 and 3, determined by ESR and ENDOR spectroscopic methods, show an extensive delocalization of the unpaired electron onto the pyrene ring.Comparison of the hfs constants of 2 and 3 shows that a more extensive delocalization of the spin into the pyrene ring takes place in 3.This is accounted for in terms of the difference in the conformations of 2 and 3.
