CORM-349 [Me4N][(OC)3Mn(mu-OCOCH3)3Mn(CO)3]; 150 mg (0.436 mmol) of Mn(CO)5(SO3CF3) and 116 mg (0.872 mmol) of [Me4N][acetate] were stirred in 8 ml of dry THF and 2 ml of methanol, under argon at 50-55 C. for 3 hrs. During this time the colour of the solution went a little darker yellow/orange.Following this, the solvent was removed on rotary evaporator to give a yellow/orange semi-solid residue. This was crystallised from DCM/Ether at -18 C. to give a yellow crystalline product (123 mg, 0.232 mmol). Yield was 100%.Based on the preliminary IR data, the product was initially identified as [Me4N][(Mn(CO)4(OAc)2]. However, additional analysis, particularly X ray crystal structure analysis, has revealed that the product has the title structure. Furthermore, mass spectral data also supports a product having more than one Mn atom.Mr=529.21.1H NMR (CD2Cl2): delta(ppm) 2.29 (s, acetate CH3 6H), 3.33 (s, NMe4 12H)13C NMR (CD2Cl2): delta(ppm) 23.55 (acetate CH3), 56.34 (NMe4), 176.15 (CO), 224.20 (CO)17O NMR (CD2Cl2): delta(ppm) 388.6 (CO)IR (CH2Cl2) nu(cm-1): 2027 (s), 1930 (vs)Mass Spec (ES-) (m/z): 455 ([Mn2(CO)6(OAc)3]-); 315 ([Mn2(CO)(OAc)3]- or [Mn2(CO)4(OAc)(OH)2]-); 257 ([Mn(CO)3(OAc)2]-)Elemental: C16H21Mn2NO12 found (calc) C: 36.80 (36.31), H: 4.90 (4.00), N: 3.60 (2.65)The dimeric structure of the anion has been established by x-ray crystallography.
