Synthesis and exchange reactions of Ni-dimine-COD, acetylene and olefin complexes

The complexes MesDADNi(COD) (1), DippDADNi(COD) (2), DippDABNiCOD (3) and DippBIANNi(COD) (5) were readily prepared from Ni(COD)2. The analogous reaction of the ligand MesBIAN afforded (MesBIAN)2Ni (4). The related Ni alkyne complexes DADNi(PhCCPh) (6), DippDABNi(PhCCPh) (7) and DippBIANNi(PhCCPh) (8) are readily prepared by addition of alkyne to solutions of the COD species. The analogous reactions employing tBuDAD ligand with either Ni(COD)2 alone or Ni(COD)2 and PhCCPh led only to the known bis-ligand Ni complex, although tBuDADNi(MeCO2CCCO 2Me) (9) is readily prepared. In a similar fashion, the species DippDADNi(MeCO2CCCO2Me) (10), DippDABNi(Me 3SiCCSiMe3) (11), DippDABNi(MeCO2CCCO 2Me) (12) and DippBIANNi(MeCO2CCCO2Me) (13) were prepared. Reactions with olefins afforded DippDABNi(MeCO 2CHCHCO2Me) (14), DippDABNi(MeCO2CHCHPh) (15). Employing isolated (3) or (15) in exchange reactions afforded (7), (11) (14) and (15). Similarly (6) served as a precursor to (10) while (11) reacts with PhCCPh to give (7). The solid state structures of (1), (3)-(7), (9), (11) and (15) are reported.

Bis(diazadiene)metal(0) Complexes, IV. Nickel(0)-bis(chelates) with Aromatic N-Substituents

With N-aromatic substituted diazadienes (DAD) (R1, R2 = H, CH3 and R3 = R4 = aryl) nickel(0) forms complexes of composition (DAD)2Ni which are prepared preferably by reduction of Ni(II) salts in the pr
