In the pyrolysis of threo-S-phenyl-S-l,l-diphenyl-2-methoxyethyl-N-ptosylsulfilimine the olefine isolated was not found to be 100% cis but contained 5.5% trans isomer 1) . This stereochemical result appears to suggest the possibility of thermal racemization of the sulfilimine at either S atom or C a
## Abstract 2β(Methylchalcogenomethyl)diphenyl selenoxides **1** and 2β{2β²β(N,Nβdimethylamino)ethyl}phenyl alkyl (or aryl) selenoxides **2**, which were expected to be stabilized toward racemization by intramolecular coordination, were synthesized and optically resolved into their enantiomers on an
