One type of these molecules can be formed from the reaction between a carbine and an imine, or the light-induced opening of an aziridine. Another one of these molecules transforms carbonyls to thiocarbonyls when the carbonyl oxygen attacks it, forming a four-membered thiaoxaphosphetane intermediate. A third example of these molecules can react with enones, imines, or ketones, to create cyclopropanes, aziridines, or epoxides, respectively. In addition to Lawesson's reagent, one of these molecules is a polar aprotic solvent whose deuterated form is used in NMR, dimethyl sulfoxide. Many of them are stabilized via a resonance structure containing a double bond, but the single-bonded structure pa

In addition to Lawesson's reagent, one of these molecules is a polar aprotic solvent whose deuterated form is used in NMR, dimethyl sulfoxide. Many of them are stabilized via a resonance structure containing a double bond, but the single-bonded structure participates more actively in chemical reactions such as the Corey-Chaykovsky reaction. For 10 points, name these types of zwitterions, one form of which is added to a carbonyl to form a Z-alkene in the Wittig reaction, which contain a negatively charged atom bonded to a positively charged atom.
