The catalysts are prepared from Ni(COD)2[31 and phosphane in the molar ratio 1 : 1. Ca. 1 mol of (I) can be converted by 1 mmol of the Ni catalyst. Apparently the C-C bond formation occurs on a LNi(o) species, since an of reaction. Accordingly, ( I ) is oligomerized only y1)cyclopropane. [4] M . En
