Abstract
Complexes such as Zr(BMP)(CH2Ph)[(eta(6)-PhCH2)B(C6F5)(3)] (BMP2- = 2, 6-bi s[(1S,2S,5R)-(-)-menthoxo]pyridyl) were synthesized and shown to undergo si ngle insertion of ethylene into their Zr-carbon bonds to yield, for example , Zr(BMP)(CH2CH2CH2Ph)][(eta(6)-PhCH2)B(C6F5)(3)], whereas alpha-olefins an d cyclooctadiene afford diastereomeric mixtures of the general formula [Zr( BMP)(eta(1):eta(6)-CHRCHR'CH2Ph)](+)[B(CH2Ph)-(C6F5)(3)](-).
