AbstractComplex Os(η5-C5H5)(C≡CPh) {[η2-CH2=C-(CH3)]PiPr 2} (1) reacts with HBF4·OEt2 to give the π-alkyne derivative [Os(η5-C5H5) (η2-HC≡CPh){η2-CH2=C(CH 3)]PiPr2}]BF4 (2), which is transformed to [Os(η5-C5H5)(1,2-dihydro-2- methylnaphth-2-yldiisopropylphosphine)]BF4 (3) as a result of the coupling of the alkyne with the isopropenyl substituent of the starting phosphine. The tridentate coordination mode of the dihydronaphthylphosphine in 3 is proved by X-ray diffraction analysis. © 2005 American Chemical Society.
