Impregnation of nickel(II) onto graphite, upon reduction in situ, leads to a reagent that catalyzes both C-H and C-C bond formations between aryl halides, or aryl pseudo-halides, and various organometallics. Cross-couplings, most notably with tosylates, can lead to either reduced aromatics, biaryls, or styrenes as products under the influence of Ni/Cg. The catalyst is inexpensive, non-pyrophoric, and
在原位还原后,将镍(II)浸渍到石墨上会产生一种试剂,该试剂既催化芳基卤化物或芳基假卤化物与各种有机金属之间的CH键和CC键形成。在Ni / Cg的影响下,交叉偶联,尤其是与甲苯磺酸酯的交叉偶联,可能导致芳族化合物,联芳基化合物或苯乙烯还原。该催化剂便宜,不发火且可重复使用。
