Abstract

Abstract Reactions between bis(allyl)nickel complexes and alkyl derivatives of 2,3-dihydro-1,3-diborole (1a, b) in refluxing toluene or mesitylene yield deeply colored solutions. By distillation and chromatography the first η3-allyl tetradecker complexes 8 were obtained in 4 -15% yield. In the violet residues higher molecular species are present, which could not be identified. The red, oily tetradeckers are characterized by NMR and mass spectra; their formation is discussed.
