Sulfones RCH(R′)SO2Ph were reacted with n-BuLi in thf/n-hexane (R/R′ = H/Me, Me/Et, H/CH2Ph) and toluene/n-hexane (R/R′ = Me/Ph) yielding under deprotonation Li[CR(R′)SO2Ph] which reacted with Me3SiCl and n-Bus

Integrated chemical process. One-pot preparation of acetylenes by Peterson-sulfone elimination

Integration of silylation of α-sulfonyl carbanion, addition of the anion of the resulting α-silyl sulfone to aldehyde, Peterson elimination, and sulfone elimination leads to one-pot synthesis of acetylenes.
