Abstract
Diisopropyl S-[(diisopropylphosphono)methyl] phosphorothiolate was dep rotonated with butyllithium. The lithiated carbanion underwent a [1,2] -sigmatropic shift, and rearranged into the (mercaptomethylene) diphos phonate anion which, by protonation, led to a (mercaptomethylene) diph osphonate. Some derivatives were prepared. (C) 1998 Elsevier Science L td. All rights reserved.
