Fi. Guseinov et al., REACTIONS OF ALPHA-FORMYL-ALPHA-CHLORCYCLONONES AND GAMMA-BUTYROLACTONE WITH S-TRIMETHYLSILYL ESTER OF DIALKYLDITHIOPHOSPHORIC ACID, Phosphorus, sulfur and silicon and the related elements, 111(1-4), 1996, pp. 837-837
alpha-Formyl-alpha-chlorsubstituted cyclonones or alpha-formyl-alpha-c
hlor-gamma-butyrolactone react with O,O-diizopropyltrimethylsilyldithi
ophosphate to give adducts which rearrange thermaly to alpha- dithioph
os phoryl contained beta-dicarbonic compounds.
