, p. 87 - 96 (1998)
The synthesis and characterization of a sterically hindered eight-membered 12H-dibenzo[d,g][1 ,3,6,2]dioxathiagermocin is described. The ΔG$273 for ring inversion (12.8 kcal.mol-1) was determined by variable temperature1H
Novel reactivity of side-on (disulfido)dicopper complexes supported by bi- and tridentate nitrogen donors: Impact of axial coordination

, p. 533 - 536 (2008/09/21)
(Figure Presented) What a difference a ligand makes: A comparison of the reactivity of the two complexes shown (Cu green, S yellow, N blue, O red, F pink, C gray) has revealed new redox processes previously unseen for copper-sulfur complexes. Furthermore, intriguing supporting-ligand effects on the properties of (disulfido)dicopper cores are uncovered.
Ethylene oxide polymerization catalyzed by aluminum complexes of sulfur-bridged polyphenols
Wasserman, Eric P.,Annis, Ioana,Chopin III, Lamy J.,Price, Philip C.,Petersen, Jeffrey L.,Abboud, Khalil A.
, p. 322 - 333 (2007/10/03)
The products derived from the reaction of sterically hindered sulfur-bridged bisphenols with aluminum trialkyls enable the efficient polymerization of ethylene oxide. The activity of the catalyst is largely determined by the structure of the bisphenol lig
