  Reactions of monoalkylnickel(II) complexes, NiR(Y)L2 (R=CH3, C2H5; Y=Cl, suc(succinimido), pht(phthalimido), OC6H4-p-CN; L=1/2 bpy (2,2′-bipyridine), PEt3 (triethylphosphine)), with CO afford monoacylnickel(II) complexes, Ni(COR)(Y)L2, which are characterized by elemental analysis and spectroscopies (IR and NMR). Reactions of the acylnickel(II) complexes with alcohols and aniline give the corresponding esters and amides, respectively. Exposure of Ni(COR)(Y)L2 to dry air leads to oxidation of RCO to a RCOO ligand giving a complex formulated as Ni(OCOR)(Y)L2. Reactions of dimethylnickel(II) complexes, Ni(CH3)2L2 (L=1/2 bpy, PEt3, 1/2 dpe (1,2-bis(diphenylphosphino)ethane, 1/2 dpp (1,3-bis(diphenylphosphino)propane), with carbon monoxide afford acetone and/or 2,3-butanedione in medium to high yields, the acetone/2,3-butanedione ratio varying with the ligand L, reaction temperature, and additives such as maleic anhydride and triphenylphosphine. Generally the acetone/2,3-butanedione ratio decreases with increase in thermal stabilities of Ni(CH3)2L2. Ni(C2H5)2(bpy) and Ni(n-C3H7)2(bpy) give 3-pentanone and 4-heptanone, respectively, on treating them with CO, whereas Ni(C2H5)2(dpe) produces C2H5CHO and C2H4.

  Zerovalent nickel compounds which feature 1,2-bis(diphenylphosphino)benzene (dppbz) were obtained via the reactivity of dppbz towards Ni(PMe3)4, which affords sequentially (dppbz)Ni(PMe3)2 and Ni(dppbz)2. Furthermore, the carbonyl derivatives (dppbz)Ni(PMe3)(CO) and (dppbz)Ni(CO)2 may be obtained via the reaction of CO with (dppbz)Ni(PMe3)2. Other methods for the synthesis of these carbonyl compounds include

  通过dppbz对Ni（PMe 3）4的反应活性获得了具有1,2-双（二苯基膦基）苯（dppbz）的零价镍化合物，依次提供了（dppbz）Ni（PMe 3）2和Ni（dppbz）2。此外，羰基衍生物（dppbz）的Ni（PME 3）（CO）和（dppbz）的Ni（CO）2可通过CO与（dppbz）的Ni（PME的反应获得3）2。合成这些羰基化合物的其他方法包括（i）通过Ni（PPh 3）2（CO）2的反应形成（dppbz）Ni（CO）2。（ii）通过（dppbz）Ni（CO）2与PMe 3反应形成（dppbz）Ni（PMe 3）（CO）。（dppbz）Ni（CO）2与其他（二膦基）Ni（CO）2化合物的ν（CO）红外光谱数据的比较为评估dppbz的电子性质提供了一种手段。具体地说，与（dppe）Ni（CO）2的比较表明，邻-亚苯基连接基产生的给电子配体比乙烯连接基略少。dppbz配体相对于其

  and aldehyde (or acetone when R = Pri) in 1 :1 :1 ratio, showing the peculiar reducing effect of alkoxide promoted by the chelating property of the phosphorus ligand. The reaction of NaOMe with [Ni(dcpe)Cl2][dcpe = 1,2-bis(dicyclohexylphosphino)-ethane] afforded mainly [Ni2(dcpe)3] when carried out in the absence of free diphosphine, and [Ni(dcpe)2] in the presence of free diphosphine. The reaction always
