The structure of 3 has been determined by X-ray diffraction. At 60 ℃ and 1.8 MPa of initial total CO/H 2 (1∶1) pressure, the catalytic activity of 3 for hydroformylation of s tyrene has also been investigated. The conversion of the styrene is 98.1%, the selectivity of the aldehydes is 99%, the 3-phenylpropyl aldehyde(n)/2-phenylpropyl aldehyde( i) mole ratio of aldehyde to 1/17.4.展开更多
