1,1-BIS(PHENYLSULFONYL)ETHYLENE Chemical Properties,Usage,Production
Uses
1,1-Bis(phenylsulfonyl)ethylene was used in the preparation of α,α-disubstituted alpha-amino acid derivatives.
Application
1,1-Bis(phenylsulfonyl)ethylene (1,1-BPSE) is a powerful Michael acceptor and dienophile; reagent for two-carbon homologation of ketones; synthetic equivalent of ethylene in Diels-Alder reactions and of ethylene 1,2-dipole in cycloadditions[1].
Preparation
1,1-Bis(phenylsulfonyl)ethylene can be prepared via careful oxidation of the corresponding ketene dithioacetal or via Mannich condensation of bis(phenylsulfonyl)methane with paraformaldehyde and a secondary amine followed by elimination with acids[2].
storage
1,1-Bis(phenylsulfonyl)ethylene keep dry and refrigerated; potential alkylating agent; use in a fume hood.
