Synthesis of new neutral and cationic monocarbonyl complexes of manganese with bipyridine ligands
摘要:
The irradiation with UV light at - 12-degrees-C of the neutral complexes fac-[Mn(CN)(CO)3(NN)] (NN = bipyridine, or 4,4'-dimethylbipyridine) in the presence of L = P(OR)3 (R = Me, Et or Ph) in CH2Cl2 gave the neutral monocarbonyls of formula trans-[Mn(CN)(CO)(NN)L2]. These complexes reacted with MeI and KPF6 in THF at room temperature to give the new cationic methyl-isocyanide monocarbonyls trans-[Mn(CNMe)(CO)(NN)L2]PF6.
