Geometrical Requirements for Nucleophilic Substitution at Bivalent sulfur(II) and sulfur(VI): An Application of the Endocyclic Restriction Test

148 p.Thesis (Ph.D.)--University of Illinois at Urbana-Champaign, 2000.These results suggest that substitution at both bivalent sulfur(II) and sulfur(VI) through a six-membered endocyclic ring is a high energy process. Thus, substitution is preferred through a linear transition state with respect to the incoming nucleophile and leaving group. A mechanism of this type would be most consistent with the classic SN2 pathway.U of I OnlyRestricted to the U of I community idenfinitely during batch ingest of legacy ETD
