An air-stable half-sandwich nickel(II) complex bearing a phosphinophenolato ligand, Cp*Ni(1,2-Ph2PC6H4O) (1), has been designed and synthesized for activation of HBpin catalytic hydroboration N-heteroarenes such as pyridine. Through addition the H–B bond across Ni–O bond, 1 reacts with to afford an 18-electron Ni(II)–H intermediate [H1(Bpin)] featuring oxygen-stabilized boron moiety, which readily reduces pyridine analogues give 1,2-hydroborated product, thus accomplishing cycle under mild...
We report an iron system, Cp*Fe(1,2-R2PC6H4X), which controls the Markovnikov and anti-Markovnikov hydrostannation of alkynes by tuning ionic metal–heteroatom bonds (Fe–X) reactivity. The sequential addition nBu3SnH to iron–amido catalyst (1, X = HN–, R Ph) affords a distannyl Fe(IV)–H species responsible for syn-addition Sn–H bond across C≡C produce branched α-vinylstannanes. Activation C(sp)–H iron–aryloxide (2, O–, Cy) iron(II) vinylidene intermediate, allowing gem-addition...
Abstract BACKGROUND: Loss of the active CuCl component occurs during acetylene dimerisation to monovinylacetylene (MVA) catalysed by an anhydrous catalyst with formation a dark red precipitate. Acidic species can reduce loss but have unfavorable influence on dimerisation. This study aims determine precipitate composition and regulate acidity find balance between reaction rate, MVA selectivity life. RESULT: The was 2CuCl·3C 2 H ·1/3CH 3 CH NH ·1/7C 7 NO, formed combination DMF, , C...
The cationic complex [Fe(P2 S2 )(NCMe)2 ](2+) (P2 =(Ph2 PC6 H4 CH2 S)2 (C2 ) ([1(NCMe)2 )), with two MeCN ligands in a cis orientation, was synthesized and characterized. ligand [1(NCMe)2 undergoes further substitution by hydride or CO to give iron(II) hydrides [H1(NCMe)](+) , [H1H](0) [H1(CO)](+) . order of reactivity the >[H1(NCMe)](+) >[H1(CO)](+) illustrated their reactions toward protic acids, organic cation 10-methylacridinium (MeAcr(+) as acceptor, intermolecular transfer among these...
The insertion of CO into the Ni–C bond synthetic Ni(II)–CH3 cationic complex ([1-CH3]+) affords a nickel–acetyl ([1-COCH3]+). Reduction resultant [1-COCH3]+ by borohydrides produces CH3CHO, CH3CH2OH, and an Ni(0) compound ([1]0), which can react with CH3I to regenerate [1-CH3]+. By conducting deuterium labeling experiments, we have demonstrated that CH3CHO is primary product from CH3CH2OH in such transformation reactions. In reduction [1-COCH3]+, formation competes loss CH4, leads Ni(0)–CO...
