Studies on Stable Sulfur Ylides. I. The Reaction of Dimethyloxo- and Dimethylsulfonium Benzoylmethylide with Aromatic Amine N-Oxides

Abstract

Dimethyloxosulfonium benzoylmethylide and dimethylsulfonium benzoylmethylide were found to react with quinoline 1-oxide in the presence of an acylating agent, producing dimethyloxosulfonium 2-quinolylbenzoylmethylide and dimethylsulfonium 2-quinolylbenzoylmethylide, respectively. Similar reaction products were obtained by the reaction of dimethyloxosulfonium benzoylmethylide with 4-methylquinoline 1-oxide, isoquinoline 2-oxide, and quinoxaline 1-oxide, but not with pyridine 1-oxide.
