Dimethylsulfoniumphenacylbromide reacts with arylisocyanates in the presence of N-ethyldiisopropylamine to stable dioxo-S-ylides (1-5). Compounds 6-16 are obtained by variation of the starting sulfonium salts and isocyanates. Tolyl-2,4-diisoyanate yields with dimethylsulfoniumphenacylbromide the 1:2 adduct 17, while with the corresponding triphenylphosphoniumbromide the 1:1 adduct 18, with a free isocyanate group, is obtained.
