Reactions of methyl fluorosulphonate and triethyloxonium tetrafluoroborate with metal complexes

Coordinated trifluoromethanesulfonate and fluorosulfate

“…133 Oxidation of the metal atom has been observed for MoC12(DPE)2 with FS03CH3, since [MoCl2(DPE)2](S03F) is the product.132 Alkylation of a coordinated ligand is also a possibility, as observed when ferricyanide reacts with FS03CH3, forming [Fe(CN)(CNCH3)5](S03F)2. 132 The attempted oxidative addition of FS03CH3 to (cp)Fe-(CO)2" did not generate (cp)Fe(C0)2(CH3)(0S02F); rather, the S-methoxysulfenate complex (cp)Fe(CO)2-(S02CH3) was identified by NMR and IR spectrosco-py,134 so S-F cleavage must be involved.…”

Synthesis of novel methyliridium(III) compounds from substitution-labile chloro(methyl)fluorosulfato(carbonylbis(triphenylphosphine)iridium(III) and chloro(methyl)trifluoromethyl sulfatocarbonylbis(triphenylphosphine)iridium(III)

“…This facile dissociation results in high lability of ch3no2 IrCl(CO)(PPh3) 2 (CH 3 )(SO 3F)(s)---V [IrCl(CO)(PPh3)2CH3]+ + S03F" (1) the methyl ñuorosulfate complex and therefore provides a route to new compounds which cannot be prepared by direct oxidative addition (eq 2). The synthetic utility of this new IrCl(CO)(PPh3)2 + CH3Y -IrCl(CO)(PPh3)2(CH3)(Y) N^so3f /y- (2) X IrCl(C0)(PPh3)2(CH3)(S03F) reaction sequence is illustrated in the present paper and structures of the products are elucidated.…”
