Donkervoort, Johannes G. published the artcileNovel tridentate diamino organomanganese(II) complexes as homogeneous catalysts in manganese(II)/copper(I) catalyzed carbon-carbon bond forming reactions, Name: (4-Bromobut-1-yn-1-yl)trimethylsilane, the publication is Journal of Organometallic Chemistry (1998), 558(1-2), 61-69, database is CAplus.
The new, paramagnetic arylmanganese(II) complex Li[MnCl2(NCN)] (2, NCN = [C6H3(CH2NMe2)2-2,6]–) was obtained in high yield from the reaction of MnCl2 and [Li(NCN)]2 in a 2:1 molar ratio. In THF solution, 2 is likely an ionic species [Li(THF)n][MnCl2(NCN)] (mol. weight determination and conductivity measurements), while magnetic measurements indicate that a high spin d5 Mn(II) center is present. Subsequent reaction of 2 with RLi afforded [MnR(NCN)] (R = Me, Bu). Complex 2, using CuCl as a co-catalyst, is an effective catalyst system for cross-coupling of Grignard reagents with alkyl bromides and the 1,4-addition of organomagnesium halides to α,β-unsaturated ketones. No further additives or co-solvents are necessary. For both reactions a dramatic decrease in reaction times is observed when compared to standard Mn/Cu systems. Alkyl bromides with unsaturated or heteroatom functionalities can be cross-coupled. Also, excellent reactivity towards normally unreactive β,β-disubstituted ketones was observed in the 1,4-addition reaction.
