Bis(triphenylphosphine)-5-nickela-3,3,7,7-tetramethyl-trans-tricyclo[4.1.0.02,4]heptane

Abstract

The oxidative addition of 3,3-dimethylcyclopropene (DMCP) to the nickel complexes (Ph3P)3Ni and (π-C2H4)Ni(PPh3)2 resulting in the formation of bis(triphenylphosphine)-5-nickela-3,3,7,7-tetramethyl-trans-tricyclo[4.1.0.02,4]heptane has been carried out. The NMR (1H and 31P-{1H}) spectra, the reactivity and some of the catalytic properties of this complex in the cyclodimerization of DMCP have been studied.
