NiBr2(dipy) [217, 218]. These experimental conditions can probably be applied to many other nickel catalysed reactions... 

The nickel-catalysed reaction of aryl, allyl or vinyl sulfides with Grignard reagents has been found to be an effective way for the conversion of carbon-sulfur bonds into carbon-carbon bonds [318]. However, simple aliphatic substrates are inert.

The nickel-catalysed reaction of organomagnesium compounds with dithioacetals, in which the initial substitution leads to elimination, giving a substituted alkene, is potentially useful [23, 24], as in the following procedure. Elimination of [3-alkoxy or alkylthio groups from the... 

G. P. Chiusoli and L. Cassar Angew. Chem. 79,177 (1967) Angew. Chem. Int. Ed. Engl. 6, 124 (1967) Nickel-catalysed reactions of allyl halides and related compounds 10 (55) ... 

In the nickel-catalysed reaction, the use of ligand with only 20% enantiomeric excess still produced a Diels-Alder adduct with up to 96% ee, which is a highly effective example of chiral amplification (see Section 6.1). 

A variety of substituted pyrroles have been synthesized by the nickel-catalysed reaction of 2//-azirines with activated ketones [equation (21)]. The product is...
