density functional theory computations. The photolysis of phenylphosphirane in 3P-O2 doped matrices enabled the spectroscopic identification of a hitherto unknown phenyldioxophosphorane, the long elusive phosphorus analogue of nitrobenzene.
三重苯基膦是通过从相应的苯基膦中光诱导消除乙烯制备的,并通过 IR 和 UV/vis 光谱以及其光谱数据与密度泛函理论计算的匹配进行表征。苯基膦在 3P-O2 掺杂的基质中的光解使迄今为止未知的苯基二氧代膦的光谱鉴定成为可能,这是硝基苯的长期难以捉摸的磷类似物。

Monocyclopentadienyl complexes in which the cyclopentadienyl system bears at least one bridged donor and at least one aryl group and a catalyst system comprising at least one of the monocyclopentad ienyl complexes, and also processes for preparing them, the use of the catalyst system for the polymerization or copolymerization of olefins and a process for preparing polyole fins by polymerization or copolymerization of olefins in the presence of the catalyst system and the preparation of the associated cyclopentadienyl system.
The present invention relates to a process for preparing hydroformylation products of olefins having at least four carbon atoms, in which a high proportion of both the linear C
i
-olefins having a terminal double bond comprised in the olefin-comprising feed used and of the linear C
i
-olefins having an internal double bond is converted into hydroformylation products. Furthermore, the invention relates to a process for preparing 2-propylheptanol which comprises such a hydroformylation process.
