Abstract: Subjecting furan to sodium-mediated magnesiation via the new heteroleptic alkyl-amido reagent [(TMEDA).Na(CH(2)SiMe(3))(TMP)Mg(TMP)] produces the remarkable dodecasodium-hexamagnesium molecule [{(TMEDA)(3)Na(6)Mg(3)(CH(2)SiMe(3))(2,5-C(4)H(2)O)(3)(2-C(4)H(3)O)(5)}(2)], built upon a bridge network of 10 monodeprotonated and 6 twofold-deprotonated furan ligands.

Abstract: More usually thought of as a base, the sodium zincate [(TMEDA)·Na(μ-TMP)(μ-(t)Bu)Zn((t)Bu)] 1 can undergo single electron transfer with TEMPO to give [(TMEDA)·Na(μ-TMP)(μ-TEMPO(-))Zn((t)Bu)] 2 and [(TMEDA)·Na(μ-TEMPO(-))(2)Zn((t)Bu)] 3 and with chalcone [PhCOCH=CHPh] gives [{(TMEDA)·Na(μ-TMP)Zn((t)Bu)}(2)(μ-OCPhCH=CHPhCHPhCH=CPh-μ-O)] which contains two chalcone units C-C coupled though their benzylic C atoms.

Abstract: The cleavage of ethers is commonly encountered in organometallic chemistry, although rarely studied in the context of new, emerging bimetallic reagents. Recently, it was reported that a bimetallic sodium-zinc base can deprotonate cyclic tetrahydrofuran under mild conditions without opening its heterocyclic (OC(4)) ring. In marked contrast to this synergic sedation, herein we show that switching to the more reactive sodium-magnesium or sodium-manganese bases promotes cleavage of at least six bonds in tetrahydrofuran, but uniquely the ring fragments are captured in separate crystalline complexes. Oxide fragments occupy guest positions in bimetallic, inverse crown ethers and C(4) fragments ultimately appear in bimetallated butadiene molecules. These results demonstrate the special synergic reactivity that can be executed by bimetallic reagents, which include the ability to capture and control, and thereby study, reactive fragments from sensitive substrates.

Abstract: With the aim of introducing the diisopropylamide [NiPr(2)](-) ligand to alkali-metal-mediated manganation (AMMMn) chemistry, the temperature-dependent reactions of a 1:1:3 mixture of butylsodium, bis(trimethylsilylmethyl)manganese(II), and diisopropylamine with ferrocene in hexane/toluene have been investigated. Performed at reflux temperature, the reaction affords the surprising, ferrocene-free, hydrido product [Na(2)Mn(2) (mu-H)(2){N(iPr)(2)}(4)]2 toluene (1), the first Mn hydrido inverse crown complex. Repeating the reaction rationally, excluding ferrocene, produces 1 in an isolated crystalline yield of 62 %. At lower temperatures, the same bimetallic amide mixture leads to the manganation of ferrocene to generate the first trimanganese, trinuclear ferrocenophane, [{Fe(C(5)H(4))(2)}(3){Mn(3)Na(2)(NiPr(2))(2) (HNiPr(2))(2)}] (2) in an isolated crystalline yield of 81 %. Both 1 and 2 have been characterised by X-ray crystallographic studies. The magnetic properties of paramagnetic 1 and 2 have also been examined by variable-temperature magnetisation measurements on powdered s les. For 1, the room-temperature value for chiT is 3.45 cm(3) K mol(-1), and on lowering the temperature a strong antiferromagnetic coupling between the two Mn ions is observed. For 2, the room-temperature value for chiT is 4.06 cm(3) K mol(-1), which is significantly lower than the expected value for three isolated paramagnetic Mn(II) ions.

Abstract: Alkali-metal-mediated manganation (AMMMn) reactions of the synergic base sodium monoalkyl-bisamidomanganate [(tmeda)Na(tmp)(CH(2)SiMe(3))Mn(tmp)] (1) with naphthalene, 1-methoxynaphthalene, or 2-methoxynaphthalene are reported. These novel direct manganation [Mn(II)] reactions produced the crystalline ortho-manganated naphthyl products [(tmeda)Na(tmp)(2-C(10)H(7))Mn(tmp)] (3), [(tmeda)Na(tmp){2-(1-MeOC(10)H(6))}Mn(CH(2)SiMe(3))] (4), and [(tmeda)Na(tmp){3-(2-MeOC(10)H(6))}Mn(tmp)] (5) in reasonable to good isolated yields of 88, 65, and 85%, respectively. All three new complexes have been crystallographically characterized, showing discrete molecular structures with trigonal planar Mn centers forming sigma bonds to the deprotonated C atoms of the naphthyl ligands, whereas Na interacts with the aromatic pi system in 3 or with the MeO substituent in 4 and 5. These latter interactions lead to interesting 5,6,7,8-tetrahydrophenanthrene-like and 1,2,3,4-tetrahydroanthracene-like metallacyclic motifs in 4 and 5, respectively. The sensitivity of these AMMMn reactions to impurities has been illustrated in the serendipitous preparation of the benzenediide complex [(tmeda)(2)Na(2)(tmp)(2)(1,4-C(6)H(4))Mn(2)(tmp)(2)] (6) from one attempted repeat synthesis of 5. An "open inverse crown" arrangement with a 1,4-dimanganated benzene molecule is revealed in the crystal structure of 6.

Abstract: Transmetallation of lithiodihydropyridines with Group 1 alkoxides provides facile access to reactive MH (M = Na, K) sources, which show significant structural ersity due in part to the distinct ways that Na/K engage with the σ (green) and π (red) donor systems of the DHP ligands.

Abstract: While lithium alkyls and lithium amides do not metallate the scandium compound [(η 5 -C 5 H 5 )Sc(η 8 -C 8 H 8 )], a synergistic lithium–aluminium base-trap partnership cannot resist taking a bite with one C–H bond selectively cleaved from both Cp and COT rings.
