This letter describes the insertion of rhodium carbenoids into thioindoles. C-10 thioindoles undergo fragmentation?coupling reactions when exposed to rhodium One of the most celebrated reactions for converting aldehydes and ketones to alkenes employs phosphorus ylides. The phosphorus ylide is sometimes referred to Jul 20, 2018 - ? Sulfur ylide: Dimethylsulfonium methylide and dimethylsulfoxonium methylide (Corey-Chaykovsky reagent) are two important types of sulfur ylides. ? Jun 20, 2015 - An ylide or ylid is a neutral dipolar molecule containing a formally negatively charged atom with a formal positive charge (usually nitrogen, phosphorus or sulfur), and in which both atoms have full octets of electrons. "A metal–amide dependent, catalytic C–H functionalisation of triphenylphosphonium methylide" (PDF). Methods for the preparation of sulfur ylides are summarized in Scheme 3-1. These methods include deprotonation of sulfonium salts, reaction of sulfur compounds The reaction of chiral sulfur ylides with aldehydes and ketones has emerged as a useful reactions of sulfur ylides with benzaldehyde.
