“…In contrast to the two-step synthesis facilitating a Wittig reagent (R 3 P + − − CR 2 ), sulfur ylides can be used as one-step epoxidating agents . Additionally, stereospecific cyclopropanation and aziridination reactions are available for activated sulfur ylide complexes. The use of sulfur ylides ((RN) 2/3 S + − − CR 2 ) allows transimidation reactions by choice of the experimental conditions (particularly the temperature)…”

“…Use of the alkoxymethyl ligand (M-CH2OR) as a source of CH2, presumably via the formation of a highly reactive, electrophilic methylene complex upon protonation or silylation, is a well-established reaction;5 related compounds are finding applications as cyclopropanation reagents. 6 The particular family of (methoxymethyl)iridium compounds we have been studying has the important feature that other reactive organic ligands, such as an olefin,4f a methyl group,4® or a hydrido hydrogen atom,4b may be coordinated adjacent to the methoxymethyl group. Protonation or silylation then causes the intramolecular reaction of the nascent methylene moiety with the bound organic ligand.…”

“…Additionally, activated sulfur ylide complexes react stereospecifically with alkenes to form cyclopropanes. [67,[92][93][94][95][96][97] Use of imines instead of alkenes leads to aziridines. [68,98,99] If imido sulfur ylides ((RN) n S + --CR 2 , n = 2, 3) are utilized, transimidation reactions are feasible by choice of the experimental conditions (particularly the temperature) as well.…”
