The first X-ray crystal structure of an O-alkyl aminosulfoxonium salt: conclusive evidence for O-alkylation of sulfinamides and planarity of nitrogen
Abstract
The X-ray crystal structure of O-methyl (2R,5R)-bis(methoxymethyl)pyrrolidin-1-yl-(S)-p-tolylaminosulfoxonium tetraphenylborate 5 is reported: this is the first X-ray crystal structure of an O-alkyl aminosulfoxonium salt, and provides conclusive evidence that alkylation of sulfinamides occurs on oxygen.
