CORRELATION OF THE TWO TORSIONAL DEGREES OF FREEDOM ABOUT THE BONDS CONNECTING THE BRIDGEHEAD CARBONS TO THE SULFUR ATOM IN BIS (9-TRIPTYCYL) SULFIDE

Article abstract of DOI:10.1016/S0040-4039(00)95752-6

Bis (9-triptycyl) sulfides were prepared by pyrolytic extrusion of sulfur dioxide from the corresponding thiosulfonates.A pair of torsional motions about the C-S bonds in these sulfides are in strict gearing and require a barrier of 29.3 kcal/mol for gear slippage.
