Abstract
N-Methyl-2-chlorobenzothiazolium tetrafluoroborate reacts with the [(Ph3P)2N]+ salt of the anion [Mn(CO)5]– to afford the cationic carbene complex [Mn(CO)5([graphic omitted])][BF4]. Treatment of the latter with a mixture of triethylamine, water, and diethyl ether yields the neutral crystalline hydride-complex [MnH(CO)4([graphic omitted])].The latter is converted into the halogeno-derivatives [MnX(CO)4([graphic omitted])](X = Cl, Br, or I) on treatment with CCl4, CH2Br2, or MeI, respectively. The iodo-complex reacts with triphenylphosphine or 4-methyl-2,6,7-trioxa-1-phosphabicyclo[2.2.2]octane to give [Mnl(CO)3L([graphic omitted])]{L = PPh3 or P[(OCH2)3CMe]}, and with thallium hexafluoroacetylacetonate to give [Mn(CO)3(hfacac)([graphic omitted])]. Some studies on the hydrido-species [MnH(CO)4([graphic omitted])] are also reported.Keywords
